Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547036, here are decompositions:

67 + 31546969 = 31547036
127 + 31546909 = 31547036
193 + 31546843 = 31547036
223 + 31546813 = 31547036
229 + 31546807 = 31547036
277 + 31546759 = 31547036
373 + 31546663 = 31547036
379 + 31546657 = 31547036

Showing the first eight; more decompositions exist.
