Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607996, here are decompositions:

127 + 31607869 = 31607996
139 + 31607857 = 31607996
157 + 31607839 = 31607996
307 + 31607689 = 31607996
313 + 31607683 = 31607996
367 + 31607629 = 31607996
397 + 31607599 = 31607996
523 + 31607473 = 31607996

Showing the first eight; more decompositions exist.
