Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489296, here are decompositions:

17 + 31489279 = 31489296
37 + 31489259 = 31489296
53 + 31489243 = 31489296
67 + 31489229 = 31489296
79 + 31489217 = 31489296
103 + 31489193 = 31489296
127 + 31489169 = 31489296
149 + 31489147 = 31489296

Showing the first eight; more decompositions exist.
