Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553922, here are decompositions:

19 + 31553903 = 31553922
89 + 31553833 = 31553922
139 + 31553783 = 31553922
163 + 31553759 = 31553922
193 + 31553729 = 31553922
251 + 31553671 = 31553922
263 + 31553659 = 31553922
313 + 31553609 = 31553922

Showing the first eight; more decompositions exist.
