Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613678, here are decompositions:

61 + 8613617 = 8613678
107 + 8613571 = 8613678
131 + 8613547 = 8613678
149 + 8613529 = 8613678
197 + 8613481 = 8613678
239 + 8613439 = 8613678
251 + 8613427 = 8613678
257 + 8613421 = 8613678

Showing the first eight; more decompositions exist.
