Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490096, here are decompositions:

3 + 31490093 = 31490096
7 + 31490089 = 31490096
19 + 31490077 = 31490096
73 + 31490023 = 31490096
97 + 31489999 = 31490096
223 + 31489873 = 31490096
277 + 31489819 = 31490096
349 + 31489747 = 31490096

Showing the first eight; more decompositions exist.
