Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607284, here are decompositions:

3 + 31607281 = 31607284
47 + 31607237 = 31607284
83 + 31607201 = 31607284
131 + 31607153 = 31607284
197 + 31607087 = 31607284
311 + 31606973 = 31607284
353 + 31606931 = 31607284
557 + 31606727 = 31607284

Showing the first eight; more decompositions exist.
