Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15770, here are decompositions:

3 + 15767 = 15770
31 + 15739 = 15770
37 + 15733 = 15770
43 + 15727 = 15770
103 + 15667 = 15770
109 + 15661 = 15770
127 + 15643 = 15770
151 + 15619 = 15770

Showing the first eight; more decompositions exist.
