Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598226, here are decompositions:

13 + 31598213 = 31598226
47 + 31598179 = 31598226
83 + 31598143 = 31598226
89 + 31598137 = 31598226
193 + 31598033 = 31598226
197 + 31598029 = 31598226
199 + 31598027 = 31598226
229 + 31597997 = 31598226

Showing the first eight; more decompositions exist.
