Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658494, here are decompositions:

181 + 8658313 = 8658494
277 + 8658217 = 8658494
571 + 8657923 = 8658494
613 + 8657881 = 8658494
643 + 8657851 = 8658494
661 + 8657833 = 8658494
727 + 8657767 = 8658494
883 + 8657611 = 8658494

Showing the first eight; more decompositions exist.
