Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608508, here are decompositions:

11 + 31608497 = 31608508
59 + 31608449 = 31608508
167 + 31608341 = 31608508
359 + 31608149 = 31608508
401 + 31608107 = 31608508
461 + 31608047 = 31608508
467 + 31608041 = 31608508
479 + 31608029 = 31608508

Showing the first eight; more decompositions exist.
