Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567472, here are decompositions:

43 + 31567429 = 31567472
61 + 31567411 = 31567472
103 + 31567369 = 31567472
193 + 31567279 = 31567472
241 + 31567231 = 31567472
499 + 31566973 = 31567472
571 + 31566901 = 31567472
709 + 31566763 = 31567472

Showing the first eight; more decompositions exist.
