Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522636, here are decompositions:

3 + 31522633 = 31522636
23 + 31522613 = 31522636
53 + 31522583 = 31522636
83 + 31522553 = 31522636
107 + 31522529 = 31522636
113 + 31522523 = 31522636
263 + 31522373 = 31522636
359 + 31522277 = 31522636

Showing the first eight; more decompositions exist.
