Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607726, here are decompositions:

37 + 31607689 = 31607726
43 + 31607683 = 31607726
97 + 31607629 = 31607726
127 + 31607599 = 31607726
223 + 31607503 = 31607726
277 + 31607449 = 31607726
433 + 31607293 = 31607726
463 + 31607263 = 31607726

Showing the first eight; more decompositions exist.
