Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597460, here are decompositions:

7 + 31597453 = 31597460
43 + 31597417 = 31597460
199 + 31597261 = 31597460
229 + 31597231 = 31597460
283 + 31597177 = 31597460
331 + 31597129 = 31597460
379 + 31597081 = 31597460
409 + 31597051 = 31597460

Showing the first eight; more decompositions exist.
