Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607448, here are decompositions:

107 + 31607341 = 31607448
139 + 31607309 = 31607448
149 + 31607299 = 31607448
151 + 31607297 = 31607448
157 + 31607291 = 31607448
167 + 31607281 = 31607448
211 + 31607237 = 31607448
241 + 31607207 = 31607448

Showing the first eight; more decompositions exist.
