Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508520, here are decompositions:

3 + 508517 = 508520
7 + 508513 = 508520
31 + 508489 = 508520
43 + 508477 = 508520
127 + 508393 = 508520
157 + 508363 = 508520
193 + 508327 = 508520
223 + 508297 = 508520

Showing the first eight; more decompositions exist.
