Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612918, here are decompositions:

79 + 8612839 = 8612918
151 + 8612767 = 8612918
211 + 8612707 = 8612918
229 + 8612689 = 8612918
277 + 8612641 = 8612918
337 + 8612581 = 8612918
421 + 8612497 = 8612918
439 + 8612479 = 8612918

Showing the first eight; more decompositions exist.
