Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606636, here are decompositions:

53 + 31606583 = 31606636
107 + 31606529 = 31606636
137 + 31606499 = 31606636
167 + 31606469 = 31606636
239 + 31606397 = 31606636
263 + 31606373 = 31606636
293 + 31606343 = 31606636
317 + 31606319 = 31606636

Showing the first eight; more decompositions exist.
