Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102650, here are decompositions:

3 + 102647 = 102650
7 + 102643 = 102650
43 + 102607 = 102650
103 + 102547 = 102650
127 + 102523 = 102650
151 + 102499 = 102650
199 + 102451 = 102650
241 + 102409 = 102650

Showing the first eight; more decompositions exist.
