Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618922, here are decompositions:

31 + 31618891 = 31618922
43 + 31618879 = 31618922
73 + 31618849 = 31618922
103 + 31618819 = 31618922
151 + 31618771 = 31618922
211 + 31618711 = 31618922
229 + 31618693 = 31618922
241 + 31618681 = 31618922

Showing the first eight; more decompositions exist.
