Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718628, here are decompositions:

47 + 8718581 = 8718628
89 + 8718539 = 8718628
137 + 8718491 = 8718628
167 + 8718461 = 8718628
197 + 8718431 = 8718628
227 + 8718401 = 8718628
251 + 8718377 = 8718628
431 + 8718197 = 8718628

Showing the first eight; more decompositions exist.
