Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607754, here are decompositions:

7 + 31607747 = 31607754
37 + 31607717 = 31607754
67 + 31607687 = 31607754
71 + 31607683 = 31607754
83 + 31607671 = 31607754
173 + 31607581 = 31607754
223 + 31607531 = 31607754
251 + 31607503 = 31607754

Showing the first eight; more decompositions exist.
