Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607116, here are decompositions:

29 + 31607087 = 31607116
137 + 31606979 = 31607116
173 + 31606943 = 31607116
197 + 31606919 = 31607116
269 + 31606847 = 31607116
389 + 31606727 = 31607116
419 + 31606697 = 31607116
449 + 31606667 = 31607116

Showing the first eight; more decompositions exist.
