Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597454, here are decompositions:

37 + 31597417 = 31597454
43 + 31597411 = 31597454
193 + 31597261 = 31597454
211 + 31597243 = 31597454
223 + 31597231 = 31597454
241 + 31597213 = 31597454
277 + 31597177 = 31597454
373 + 31597081 = 31597454

Showing the first eight; more decompositions exist.
