Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712328, here are decompositions:

5 + 8712323 = 8712328
17 + 8712311 = 8712328
41 + 8712287 = 8712328
47 + 8712281 = 8712328
59 + 8712269 = 8712328
71 + 8712257 = 8712328
101 + 8712227 = 8712328
179 + 8712149 = 8712328

Showing the first eight; more decompositions exist.
