Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607658, here are decompositions:

29 + 31607629 = 31607658
59 + 31607599 = 31607658
79 + 31607579 = 31607658
107 + 31607551 = 31607658
127 + 31607531 = 31607658
197 + 31607461 = 31607658
211 + 31607447 = 31607658
317 + 31607341 = 31607658

Showing the first eight; more decompositions exist.
