Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485922, here are decompositions:

5 + 31485917 = 31485922
29 + 31485893 = 31485922
89 + 31485833 = 31485922
131 + 31485791 = 31485922
173 + 31485749 = 31485922
179 + 31485743 = 31485922
269 + 31485653 = 31485922
311 + 31485611 = 31485922

Showing the first eight; more decompositions exist.
