Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506964, here are decompositions:

53 + 31506911 = 31506964
173 + 31506791 = 31506964
443 + 31506521 = 31506964
521 + 31506443 = 31506964
653 + 31506311 = 31506964
701 + 31506263 = 31506964
971 + 31505993 = 31506964
1151 + 31505813 = 31506964

Showing the first eight; more decompositions exist.
