Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629942, here are decompositions:

53 + 8629889 = 8629942
59 + 8629883 = 8629942
179 + 8629763 = 8629942
263 + 8629679 = 8629942
281 + 8629661 = 8629942
359 + 8629583 = 8629942
509 + 8629433 = 8629942
593 + 8629349 = 8629942

Showing the first eight; more decompositions exist.
