Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617826, here are decompositions:

3 + 8617823 = 8617826
73 + 8617753 = 8617826
127 + 8617699 = 8617826
199 + 8617627 = 8617826
277 + 8617549 = 8617826
307 + 8617519 = 8617826
313 + 8617513 = 8617826
379 + 8617447 = 8617826

Showing the first eight; more decompositions exist.
