Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567668, here are decompositions:

19 + 31567649 = 31567668
31 + 31567637 = 31567668
47 + 31567621 = 31567668
109 + 31567559 = 31567668
157 + 31567511 = 31567668
239 + 31567429 = 31567668
241 + 31567427 = 31567668
257 + 31567411 = 31567668

Showing the first eight; more decompositions exist.
