Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608616, here are decompositions:

29 + 31608587 = 31608616
89 + 31608527 = 31608616
167 + 31608449 = 31608616
353 + 31608263 = 31608616
449 + 31608167 = 31608616
467 + 31608149 = 31608616
509 + 31608107 = 31608616
569 + 31608047 = 31608616

Showing the first eight; more decompositions exist.
