Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508518, here are decompositions:

5 + 508513 = 508518
19 + 508499 = 508518
29 + 508489 = 508518
41 + 508477 = 508518
47 + 508471 = 508518
67 + 508451 = 508518
79 + 508439 = 508518
151 + 508367 = 508518

Showing the first eight; more decompositions exist.
