Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608636, here are decompositions:

47 + 31608589 = 31608636
107 + 31608529 = 31608636
109 + 31608527 = 31608636
139 + 31608497 = 31608636
317 + 31608319 = 31608636
373 + 31608263 = 31608636
419 + 31608217 = 31608636
467 + 31608169 = 31608636

Showing the first eight; more decompositions exist.
