Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493976, here are decompositions:

67 + 31493909 = 31493976
193 + 31493783 = 31493976
197 + 31493779 = 31493976
233 + 31493743 = 31493976
383 + 31493593 = 31493976
419 + 31493557 = 31493976
443 + 31493533 = 31493976
457 + 31493519 = 31493976

Showing the first eight; more decompositions exist.
