Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598290, here are decompositions:

11 + 31598279 = 31598290
23 + 31598267 = 31598290
29 + 31598261 = 31598290
89 + 31598201 = 31598290
149 + 31598141 = 31598290
233 + 31598057 = 31598290
257 + 31598033 = 31598290
263 + 31598027 = 31598290

Showing the first eight; more decompositions exist.
