Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598284, here are decompositions:

5 + 31598279 = 31598284
17 + 31598267 = 31598284
23 + 31598261 = 31598284
71 + 31598213 = 31598284
83 + 31598201 = 31598284
227 + 31598057 = 31598284
251 + 31598033 = 31598284
257 + 31598027 = 31598284

Showing the first eight; more decompositions exist.
