Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508422, here are decompositions:

5 + 31508417 = 31508422
59 + 31508363 = 31508422
191 + 31508231 = 31508422
251 + 31508171 = 31508422
263 + 31508159 = 31508422
269 + 31508153 = 31508422
383 + 31508039 = 31508422
419 + 31508003 = 31508422

Showing the first eight; more decompositions exist.
