Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538518, here are decompositions:

5 + 538513 = 538518
7 + 538511 = 538518
31 + 538487 = 538518
37 + 538481 = 538518
47 + 538471 = 538518
61 + 538457 = 538518
107 + 538411 = 538518
151 + 538367 = 538518

Showing the first eight; more decompositions exist.
