Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152808, here are decompositions:

17 + 152791 = 152808
31 + 152777 = 152808
41 + 152767 = 152808
79 + 152729 = 152808
127 + 152681 = 152808
137 + 152671 = 152808
151 + 152657 = 152808
167 + 152641 = 152808

Showing the first eight; more decompositions exist.
