Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713490, here are decompositions:

3 + 8713487 = 8713490
31 + 8713459 = 8713490
43 + 8713447 = 8713490
61 + 8713429 = 8713490
127 + 8713363 = 8713490
151 + 8713339 = 8713490
199 + 8713291 = 8713490
229 + 8713261 = 8713490

Showing the first eight; more decompositions exist.
