Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598310, here are decompositions:

11 + 31598299 = 31598310
31 + 31598279 = 31598310
43 + 31598267 = 31598310
71 + 31598239 = 31598310
83 + 31598227 = 31598310
97 + 31598213 = 31598310
109 + 31598201 = 31598310
131 + 31598179 = 31598310

Showing the first eight; more decompositions exist.
