Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712288, here are decompositions:

7 + 8712281 = 8712288
19 + 8712269 = 8712288
29 + 8712259 = 8712288
31 + 8712257 = 8712288
59 + 8712229 = 8712288
61 + 8712227 = 8712288
107 + 8712181 = 8712288
131 + 8712157 = 8712288

Showing the first eight; more decompositions exist.
