Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15650, here are decompositions:

3 + 15647 = 15650
7 + 15643 = 15650
31 + 15619 = 15650
43 + 15607 = 15650
67 + 15583 = 15650
109 + 15541 = 15650
139 + 15511 = 15650
157 + 15493 = 15650

Showing the first eight; more decompositions exist.
