Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448108, here are decompositions:

37 + 31448071 = 31448108
151 + 31447957 = 31448108
157 + 31447951 = 31448108
271 + 31447837 = 31448108
631 + 31447477 = 31448108
751 + 31447357 = 31448108
919 + 31447189 = 31448108
1009 + 31447099 = 31448108

Showing the first eight; more decompositions exist.
