Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485022, here are decompositions:

3 + 31485019 = 31485022
5 + 31485017 = 31485022
29 + 31484993 = 31485022
251 + 31484771 = 31485022
269 + 31484753 = 31485022
281 + 31484741 = 31485022
311 + 31484711 = 31485022
479 + 31484543 = 31485022

Showing the first eight; more decompositions exist.
