Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448154, here are decompositions:

5 + 31448149 = 31448154
13 + 31448141 = 31448154
43 + 31448111 = 31448154
83 + 31448071 = 31448154
97 + 31448057 = 31448154
131 + 31448023 = 31448154
137 + 31448017 = 31448154
167 + 31447987 = 31448154

Showing the first eight; more decompositions exist.
