Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607292, here are decompositions:

11 + 31607281 = 31607292
29 + 31607263 = 31607292
139 + 31607153 = 31607292
191 + 31607101 = 31607292
313 + 31606979 = 31607292
349 + 31606943 = 31607292
373 + 31606919 = 31607292
389 + 31606903 = 31607292

Showing the first eight; more decompositions exist.
