Solaris 10 top more free memory than real

When I type TOP command in my server I get result:

CPU states: 79.3% idle,  9.2% user, 11.6% kernel,  0.0% iowait,  0.0% swap
Memory: 16G real, 19G free, 283G swap in use, 115G swap free

I don't have free command as well as /etc/meminfo file. My question is what can cause bigger value of Free memory than real is?

Solaris has different attitude in representing memory, I strongly encourage you use below instruction to get Mem info

# echo ::memstat | mdb -k
