Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448118, here are decompositions:

7 + 31448111 = 31448118
47 + 31448071 = 31448118
61 + 31448057 = 31448118
101 + 31448017 = 31448118
131 + 31447987 = 31448118
151 + 31447967 = 31448118
157 + 31447961 = 31448118
167 + 31447951 = 31448118

Showing the first eight; more decompositions exist.
