Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597054, here are decompositions:

3 + 31597051 = 31597054
11 + 31597043 = 31597054
23 + 31597031 = 31597054
131 + 31596923 = 31597054
173 + 31596881 = 31597054
197 + 31596857 = 31597054
233 + 31596821 = 31597054
257 + 31596797 = 31597054

Showing the first eight; more decompositions exist.
