Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543748, here are decompositions:

37 + 31543711 = 31543748
79 + 31543669 = 31543748
541 + 31543207 = 31543748
739 + 31543009 = 31543748
757 + 31542991 = 31543748
811 + 31542937 = 31543748
919 + 31542829 = 31543748
937 + 31542811 = 31543748

Showing the first eight; more decompositions exist.
