Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608628, here are decompositions:

41 + 31608587 = 31608628
101 + 31608527 = 31608628
131 + 31608497 = 31608628
179 + 31608449 = 31608628
461 + 31608167 = 31608628
479 + 31608149 = 31608628
521 + 31608107 = 31608628
587 + 31608041 = 31608628

Showing the first eight; more decompositions exist.
