Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532922, here are decompositions:

23 + 31532899 = 31532922
41 + 31532881 = 31532922
59 + 31532863 = 31532922
89 + 31532833 = 31532922
173 + 31532749 = 31532922
229 + 31532693 = 31532922
263 + 31532659 = 31532922
269 + 31532653 = 31532922

Showing the first eight; more decompositions exist.
