Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597082, here are decompositions:

31 + 31597051 = 31597082
79 + 31597003 = 31597082
193 + 31596889 = 31597082
199 + 31596883 = 31597082
313 + 31596769 = 31597082
331 + 31596751 = 31597082
373 + 31596709 = 31597082
409 + 31596673 = 31597082

Showing the first eight; more decompositions exist.
