Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607502, here are decompositions:

13 + 31607489 = 31607502
29 + 31607473 = 31607502
41 + 31607461 = 31607502
53 + 31607449 = 31607502
79 + 31607423 = 31607502
103 + 31607399 = 31607502
139 + 31607363 = 31607502
193 + 31607309 = 31607502

Showing the first eight; more decompositions exist.
