Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588206, here are decompositions:

5 + 31588201 = 31588206
7 + 31588199 = 31588206
103 + 31588103 = 31588206
227 + 31587979 = 31588206
257 + 31587949 = 31588206
263 + 31587943 = 31588206
283 + 31587923 = 31588206
313 + 31587893 = 31588206

Showing the first eight; more decompositions exist.
