Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607952, here are decompositions:

31 + 31607921 = 31607952
43 + 31607909 = 31607952
83 + 31607869 = 31607952
113 + 31607839 = 31607952
163 + 31607789 = 31607952
263 + 31607689 = 31607952
269 + 31607683 = 31607952
281 + 31607671 = 31607952

Showing the first eight; more decompositions exist.
