Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625634, here are decompositions:

47 + 8625587 = 8625634
107 + 8625527 = 8625634
113 + 8625521 = 8625634
167 + 8625467 = 8625634
317 + 8625317 = 8625634
401 + 8625233 = 8625634
431 + 8625203 = 8625634
443 + 8625191 = 8625634

Showing the first eight; more decompositions exist.
