Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573814, here are decompositions:

61 + 31573753 = 31573814
67 + 31573747 = 31573814
193 + 31573621 = 31573814
313 + 31573501 = 31573814
421 + 31573393 = 31573814
457 + 31573357 = 31573814
661 + 31573153 = 31573814
691 + 31573123 = 31573814

Showing the first eight; more decompositions exist.
