Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650490, here are decompositions:

3 + 8650487 = 8650490
31 + 8650459 = 8650490
61 + 8650429 = 8650490
67 + 8650423 = 8650490
181 + 8650309 = 8650490
271 + 8650219 = 8650490
337 + 8650153 = 8650490
349 + 8650141 = 8650490

Showing the first eight; more decompositions exist.
