Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607670, here are decompositions:

41 + 31607629 = 31607670
71 + 31607599 = 31607670
89 + 31607581 = 31607670
139 + 31607531 = 31607670
167 + 31607503 = 31607670
181 + 31607489 = 31607670
197 + 31607473 = 31607670
223 + 31607447 = 31607670

Showing the first eight; more decompositions exist.
