Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608610, here are decompositions:

23 + 31608587 = 31608610
83 + 31608527 = 31608610
113 + 31608497 = 31608610
269 + 31608341 = 31608610
347 + 31608263 = 31608610
443 + 31608167 = 31608610
461 + 31608149 = 31608610
479 + 31608131 = 31608610

Showing the first eight; more decompositions exist.
