Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712340, here are decompositions:

3 + 8712337 = 8712340
17 + 8712323 = 8712340
29 + 8712311 = 8712340
47 + 8712293 = 8712340
53 + 8712287 = 8712340
59 + 8712281 = 8712340
71 + 8712269 = 8712340
83 + 8712257 = 8712340

Showing the first eight; more decompositions exist.
