Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567674, here are decompositions:

31 + 31567643 = 31567674
37 + 31567637 = 31567674
53 + 31567621 = 31567674
71 + 31567603 = 31567674
163 + 31567511 = 31567674
223 + 31567451 = 31567674
263 + 31567411 = 31567674
277 + 31567397 = 31567674

Showing the first eight; more decompositions exist.
