Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617984, here are decompositions:

41 + 8617943 = 8617984
107 + 8617877 = 8617984
113 + 8617871 = 8617984
197 + 8617787 = 8617984
281 + 8617703 = 8617984
461 + 8617523 = 8617984
587 + 8617397 = 8617984
593 + 8617391 = 8617984

Showing the first eight; more decompositions exist.
