Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567508, here are decompositions:

79 + 31567429 = 31567508
97 + 31567411 = 31567508
139 + 31567369 = 31567508
211 + 31567297 = 31567508
229 + 31567279 = 31567508
241 + 31567267 = 31567508
277 + 31567231 = 31567508
421 + 31567087 = 31567508

Showing the first eight; more decompositions exist.
