Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533844, here are decompositions:

5 + 31533839 = 31533844
11 + 31533833 = 31533844
53 + 31533791 = 31533844
71 + 31533773 = 31533844
137 + 31533707 = 31533844
233 + 31533611 = 31533844
257 + 31533587 = 31533844
263 + 31533581 = 31533844

Showing the first eight; more decompositions exist.
