Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543096, here are decompositions:

17 + 31543079 = 31543096
29 + 31543067 = 31543096
239 + 31542857 = 31543096
269 + 31542827 = 31543096
419 + 31542677 = 31543096
509 + 31542587 = 31543096
587 + 31542509 = 31543096
617 + 31542479 = 31543096

Showing the first eight; more decompositions exist.
