Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567670, here are decompositions:

67 + 31567603 = 31567670
157 + 31567513 = 31567670
241 + 31567429 = 31567670
373 + 31567297 = 31567670
439 + 31567231 = 31567670
457 + 31567213 = 31567670
691 + 31566979 = 31567670
751 + 31566919 = 31567670

Showing the first eight; more decompositions exist.
