Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448174, here are decompositions:

3 + 31448171 = 31448174
13 + 31448161 = 31448174
103 + 31448071 = 31448174
151 + 31448023 = 31448174
157 + 31448017 = 31448174
211 + 31447963 = 31448174
223 + 31447951 = 31448174
271 + 31447903 = 31448174

Showing the first eight; more decompositions exist.
