Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460836, here are decompositions:

3 + 31460833 = 31460836
5 + 31460831 = 31460836
53 + 31460783 = 31460836
107 + 31460729 = 31460836
179 + 31460657 = 31460836
227 + 31460609 = 31460836
353 + 31460483 = 31460836
467 + 31460369 = 31460836

Showing the first eight; more decompositions exist.
