Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513296, here are decompositions:

37 + 31513259 = 31513296
83 + 31513213 = 31513296
103 + 31513193 = 31513296
109 + 31513187 = 31513296
149 + 31513147 = 31513296
173 + 31513123 = 31513296
179 + 31513117 = 31513296
223 + 31513073 = 31513296

Showing the first eight; more decompositions exist.
