Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607232, here are decompositions:

5 + 31607227 = 31607232
31 + 31607201 = 31607232
79 + 31607153 = 31607232
131 + 31607101 = 31607232
193 + 31607039 = 31607232
269 + 31606963 = 31607232
281 + 31606951 = 31607232
313 + 31606919 = 31607232

Showing the first eight; more decompositions exist.
