Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520488, here are decompositions:

37 + 520451 = 520488
41 + 520447 = 520488
61 + 520427 = 520488
79 + 520409 = 520488
107 + 520381 = 520488
109 + 520379 = 520488
127 + 520361 = 520488
131 + 520357 = 520488

Showing the first eight; more decompositions exist.
