Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598156, here are decompositions:

13 + 31598143 = 31598156
19 + 31598137 = 31598156
127 + 31598029 = 31598156
223 + 31597933 = 31598156
229 + 31597927 = 31598156
277 + 31597879 = 31598156
283 + 31597873 = 31598156
313 + 31597843 = 31598156

Showing the first eight; more decompositions exist.
