Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597614, here are decompositions:

11 + 31597603 = 31597614
43 + 31597571 = 31597614
73 + 31597541 = 31597614
107 + 31597507 = 31597614
131 + 31597483 = 31597614
197 + 31597417 = 31597614
277 + 31597337 = 31597614
331 + 31597283 = 31597614

Showing the first eight; more decompositions exist.
