Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541922, here are decompositions:

19 + 31541903 = 31541922
23 + 31541899 = 31541922
29 + 31541893 = 31541922
31 + 31541891 = 31541922
53 + 31541869 = 31541922
229 + 31541693 = 31541922
263 + 31541659 = 31541922
271 + 31541651 = 31541922

Showing the first eight; more decompositions exist.
