Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510518, here are decompositions:

37 + 510481 = 510518
61 + 510457 = 510518
67 + 510451 = 510518
139 + 510379 = 510518
157 + 510361 = 510518
199 + 510319 = 510518
271 + 510247 = 510518
277 + 510241 = 510518

Showing the first eight; more decompositions exist.
