Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473956, here are decompositions:

109 + 31473847 = 31473956
223 + 31473733 = 31473956
373 + 31473583 = 31473956
433 + 31473523 = 31473956
499 + 31473457 = 31473956
643 + 31473313 = 31473956
673 + 31473283 = 31473956
739 + 31473217 = 31473956

Showing the first eight; more decompositions exist.
