Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607302, here are decompositions:

3 + 31607299 = 31607302
5 + 31607297 = 31607302
11 + 31607291 = 31607302
101 + 31607201 = 31607302
149 + 31607153 = 31607302
263 + 31607039 = 31607302
359 + 31606943 = 31607302
383 + 31606919 = 31607302

Showing the first eight; more decompositions exist.
