Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597382, here are decompositions:

139 + 31597243 = 31597382
151 + 31597231 = 31597382
283 + 31597099 = 31597382
331 + 31597051 = 31597382
379 + 31597003 = 31597382
433 + 31596949 = 31597382
499 + 31596883 = 31597382
613 + 31596769 = 31597382

Showing the first eight; more decompositions exist.
