Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678528, here are decompositions:

349 + 8678179 = 8678528
367 + 8678161 = 8678528
379 + 8678149 = 8678528
499 + 8678029 = 8678528
577 + 8677951 = 8678528
757 + 8677771 = 8678528
769 + 8677759 = 8678528
877 + 8677651 = 8678528

Showing the first eight; more decompositions exist.
