Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607866, here are decompositions:

83 + 31607783 = 31607866
149 + 31607717 = 31607866
179 + 31607687 = 31607866
419 + 31607447 = 31607866
443 + 31607423 = 31607866
467 + 31607399 = 31607866
503 + 31607363 = 31607866
509 + 31607357 = 31607866

Showing the first eight; more decompositions exist.
