Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620634, here are decompositions:

3 + 8620631 = 8620634
13 + 8620621 = 8620634
31 + 8620603 = 8620634
67 + 8620567 = 8620634
241 + 8620393 = 8620634
307 + 8620327 = 8620634
367 + 8620267 = 8620634
523 + 8620111 = 8620634

Showing the first eight; more decompositions exist.
