Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533886, here are decompositions:

47 + 31533839 = 31533886
53 + 31533833 = 31533886
113 + 31533773 = 31533886
179 + 31533707 = 31533886
227 + 31533659 = 31533886
353 + 31533533 = 31533886
389 + 31533497 = 31533886
617 + 31533269 = 31533886

Showing the first eight; more decompositions exist.
