Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510138, here are decompositions:

11 + 510127 = 510138
17 + 510121 = 510138
37 + 510101 = 510138
59 + 510079 = 510138
61 + 510077 = 510138
71 + 510067 = 510138
89 + 510049 = 510138
107 + 510031 = 510138

Showing the first eight; more decompositions exist.
