Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448360, here are decompositions:

37 + 31448323 = 31448360
61 + 31448299 = 31448360
67 + 31448293 = 31448360
79 + 31448281 = 31448360
127 + 31448233 = 31448360
199 + 31448161 = 31448360
211 + 31448149 = 31448360
337 + 31448023 = 31448360

Showing the first eight; more decompositions exist.
