Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510156, here are decompositions:

19 + 510137 = 510156
29 + 510127 = 510156
67 + 510089 = 510156
79 + 510077 = 510156
83 + 510073 = 510156
89 + 510067 = 510156
107 + 510049 = 510156
109 + 510047 = 510156

Showing the first eight; more decompositions exist.
