Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607182, here are decompositions:

29 + 31607153 = 31607182
239 + 31606943 = 31607182
251 + 31606931 = 31607182
263 + 31606919 = 31607182
353 + 31606829 = 31607182
479 + 31606703 = 31607182
491 + 31606691 = 31607182
521 + 31606661 = 31607182

Showing the first eight; more decompositions exist.
