Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607450, here are decompositions:

3 + 31607447 = 31607450
109 + 31607341 = 31607450
151 + 31607299 = 31607450
157 + 31607293 = 31607450
223 + 31607227 = 31607450
313 + 31607137 = 31607450
349 + 31607101 = 31607450
487 + 31606963 = 31607450

Showing the first eight; more decompositions exist.
