Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567466, here are decompositions:

37 + 31567429 = 31567466
97 + 31567369 = 31567466
199 + 31567267 = 31567466
313 + 31567153 = 31567466
379 + 31567087 = 31567466
487 + 31566979 = 31567466
499 + 31566967 = 31567466
547 + 31566919 = 31567466

Showing the first eight; more decompositions exist.
