Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712318, here are decompositions:

7 + 8712311 = 8712318
11 + 8712307 = 8712318
31 + 8712287 = 8712318
37 + 8712281 = 8712318
59 + 8712259 = 8712318
61 + 8712257 = 8712318
89 + 8712229 = 8712318
137 + 8712181 = 8712318

Showing the first eight; more decompositions exist.
