Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629868, here are decompositions:

97 + 8629771 = 8629868
157 + 8629711 = 8629868
271 + 8629597 = 8629868
307 + 8629561 = 8629868
421 + 8629447 = 8629868
439 + 8629429 = 8629868
571 + 8629297 = 8629868
727 + 8629141 = 8629868

Showing the first eight; more decompositions exist.
