Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712230, here are decompositions:

3 + 8712227 = 8712230
61 + 8712169 = 8712230
67 + 8712163 = 8712230
73 + 8712157 = 8712230
97 + 8712133 = 8712230
139 + 8712091 = 8712230
211 + 8712019 = 8712230
277 + 8711953 = 8712230

Showing the first eight; more decompositions exist.
