Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607250, here are decompositions:

13 + 31607237 = 31607250
23 + 31607227 = 31607250
43 + 31607207 = 31607250
97 + 31607153 = 31607250
113 + 31607137 = 31607250
149 + 31607101 = 31607250
163 + 31607087 = 31607250
211 + 31607039 = 31607250

Showing the first eight; more decompositions exist.
