Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87650, here are decompositions:

7 + 87643 = 87650
19 + 87631 = 87650
37 + 87613 = 87650
61 + 87589 = 87650
67 + 87583 = 87650
97 + 87553 = 87650
103 + 87547 = 87650
109 + 87541 = 87650

Showing the first eight; more decompositions exist.
