Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608634, here are decompositions:

47 + 31608587 = 31608634
107 + 31608527 = 31608634
137 + 31608497 = 31608634
293 + 31608341 = 31608634
467 + 31608167 = 31608634
503 + 31608131 = 31608634
587 + 31608047 = 31608634
593 + 31608041 = 31608634

Showing the first eight; more decompositions exist.
