Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484922, here are decompositions:

11 + 31484911 = 31484922
19 + 31484903 = 31484922
59 + 31484863 = 31484922
83 + 31484839 = 31484922
101 + 31484821 = 31484922
151 + 31484771 = 31484922
181 + 31484741 = 31484922
211 + 31484711 = 31484922

Showing the first eight; more decompositions exist.
