Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608496, here are decompositions:

47 + 31608449 = 31608496
233 + 31608263 = 31608496
347 + 31608149 = 31608496
389 + 31608107 = 31608496
449 + 31608047 = 31608496
467 + 31608029 = 31608496
587 + 31607909 = 31608496
593 + 31607903 = 31608496

Showing the first eight; more decompositions exist.
