Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597406, here are decompositions:

163 + 31597243 = 31597406
193 + 31597213 = 31597406
229 + 31597177 = 31597406
277 + 31597129 = 31597406
307 + 31597099 = 31597406
409 + 31596997 = 31597406
457 + 31596949 = 31597406
499 + 31596907 = 31597406

Showing the first eight; more decompositions exist.
