Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510278, here are decompositions:

7 + 510271 = 510278
31 + 510247 = 510278
37 + 510241 = 510278
61 + 510217 = 510278
79 + 510199 = 510278
151 + 510127 = 510278
157 + 510121 = 510278
199 + 510079 = 510278

Showing the first eight; more decompositions exist.
