Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567268, here are decompositions:

37 + 31567231 = 31567268
181 + 31567087 = 31567268
349 + 31566919 = 31567268
367 + 31566901 = 31567268
709 + 31566559 = 31567268
727 + 31566541 = 31567268
751 + 31566517 = 31567268
787 + 31566481 = 31567268

Showing the first eight; more decompositions exist.
