Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508878, here are decompositions:

11 + 508867 = 508878
31 + 508847 = 508878
37 + 508841 = 508878
61 + 508817 = 508878
67 + 508811 = 508878
79 + 508799 = 508878
89 + 508789 = 508878
107 + 508771 = 508878

Showing the first eight; more decompositions exist.
