Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608376, here are decompositions:

113 + 31608263 = 31608376
227 + 31608149 = 31608376
269 + 31608107 = 31608376
347 + 31608029 = 31608376
467 + 31607909 = 31608376
479 + 31607897 = 31608376
509 + 31607867 = 31608376
587 + 31607789 = 31608376

Showing the first eight; more decompositions exist.
