Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607722, here are decompositions:

5 + 31607717 = 31607722
191 + 31607531 = 31607722
233 + 31607489 = 31607722
359 + 31607363 = 31607722
431 + 31607291 = 31607722
521 + 31607201 = 31607722
569 + 31607153 = 31607722
683 + 31607039 = 31607722

Showing the first eight; more decompositions exist.
