Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508402, here are decompositions:

29 + 508373 = 508402
53 + 508349 = 508402
71 + 508331 = 508402
101 + 508301 = 508402
131 + 508271 = 508402
173 + 508229 = 508402
179 + 508223 = 508402
311 + 508091 = 508402

Showing the first eight; more decompositions exist.
