Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617790, here are decompositions:

3 + 8617787 = 8617790
37 + 8617753 = 8617790
109 + 8617681 = 8617790
163 + 8617627 = 8617790
229 + 8617561 = 8617790
241 + 8617549 = 8617790
271 + 8617519 = 8617790
277 + 8617513 = 8617790

Showing the first eight; more decompositions exist.
