Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448202, here are decompositions:

11 + 31448191 = 31448202
31 + 31448171 = 31448202
41 + 31448161 = 31448202
53 + 31448149 = 31448202
61 + 31448141 = 31448202
131 + 31448071 = 31448202
179 + 31448023 = 31448202
239 + 31447963 = 31448202

Showing the first eight; more decompositions exist.
