Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607492, here are decompositions:

3 + 31607489 = 31607492
19 + 31607473 = 31607492
31 + 31607461 = 31607492
43 + 31607449 = 31607492
151 + 31607341 = 31607492
193 + 31607299 = 31607492
199 + 31607293 = 31607492
211 + 31607281 = 31607492

Showing the first eight; more decompositions exist.
