Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607132, here are decompositions:

31 + 31607101 = 31607132
181 + 31606951 = 31607132
229 + 31606903 = 31607132
379 + 31606753 = 31607132
421 + 31606711 = 31607132
709 + 31606423 = 31607132
751 + 31606381 = 31607132
853 + 31606279 = 31607132

Showing the first eight; more decompositions exist.
