Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598250, here are decompositions:

11 + 31598239 = 31598250
23 + 31598227 = 31598250
37 + 31598213 = 31598250
59 + 31598191 = 31598250
71 + 31598179 = 31598250
107 + 31598143 = 31598250
109 + 31598141 = 31598250
113 + 31598137 = 31598250

Showing the first eight; more decompositions exist.
