Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617958, here are decompositions:

31 + 8617927 = 8617958
277 + 8617681 = 8617958
331 + 8617627 = 8617958
397 + 8617561 = 8617958
409 + 8617549 = 8617958
439 + 8617519 = 8617958
541 + 8617417 = 8617958
577 + 8617381 = 8617958

Showing the first eight; more decompositions exist.
