Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508660, here are decompositions:

17 + 508643 = 508660
23 + 508637 = 508660
41 + 508619 = 508660
83 + 508577 = 508660
101 + 508559 = 508660
227 + 508433 = 508660
293 + 508367 = 508660
311 + 508349 = 508660

Showing the first eight; more decompositions exist.
