Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627812, here are decompositions:

3 + 8627809 = 8627812
5 + 8627807 = 8627812
71 + 8627741 = 8627812
113 + 8627699 = 8627812
131 + 8627681 = 8627812
173 + 8627639 = 8627812
239 + 8627573 = 8627812
251 + 8627561 = 8627812

Showing the first eight; more decompositions exist.
