Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712188, here are decompositions:

7 + 8712181 = 8712188
19 + 8712169 = 8712188
31 + 8712157 = 8712188
97 + 8712091 = 8712188
337 + 8711851 = 8712188
367 + 8711821 = 8712188
421 + 8711767 = 8712188
439 + 8711749 = 8712188

Showing the first eight; more decompositions exist.
