Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508940, here are decompositions:

31 + 508909 = 508940
37 + 508903 = 508940
73 + 508867 = 508940
151 + 508789 = 508940
373 + 508567 = 508940
409 + 508531 = 508940
463 + 508477 = 508940
547 + 508393 = 508940

Showing the first eight; more decompositions exist.
