Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598308, here are decompositions:

29 + 31598279 = 31598308
41 + 31598267 = 31598308
47 + 31598261 = 31598308
107 + 31598201 = 31598308
167 + 31598141 = 31598308
251 + 31598057 = 31598308
281 + 31598027 = 31598308
311 + 31597997 = 31598308

Showing the first eight; more decompositions exist.
