Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567302, here are decompositions:

5 + 31567297 = 31567302
23 + 31567279 = 31567302
31 + 31567271 = 31567302
61 + 31567241 = 31567302
71 + 31567231 = 31567302
83 + 31567219 = 31567302
89 + 31567213 = 31567302
149 + 31567153 = 31567302

Showing the first eight; more decompositions exist.
