Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613690, here are decompositions:

13 + 8613677 = 8613690
67 + 8613623 = 8613690
73 + 8613617 = 8613690
131 + 8613559 = 8613690
227 + 8613463 = 8613690
229 + 8613461 = 8613690
233 + 8613457 = 8613690
251 + 8613439 = 8613690

Showing the first eight; more decompositions exist.
