Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630626, here are decompositions:

107 + 8630519 = 8630626
149 + 8630477 = 8630626
239 + 8630387 = 8630626
383 + 8630243 = 8630626
419 + 8630207 = 8630626
449 + 8630177 = 8630626
467 + 8630159 = 8630626
509 + 8630117 = 8630626

Showing the first eight; more decompositions exist.
