Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567330, here are decompositions:

17 + 31567313 = 31567330
59 + 31567271 = 31567330
89 + 31567241 = 31567330
173 + 31567157 = 31567330
239 + 31567091 = 31567330
281 + 31567049 = 31567330
419 + 31566911 = 31567330
467 + 31566863 = 31567330

Showing the first eight; more decompositions exist.
