Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597502, here are decompositions:

19 + 31597483 = 31597502
31 + 31597471 = 31597502
241 + 31597261 = 31597502
271 + 31597231 = 31597502
373 + 31597129 = 31597502
421 + 31597081 = 31597502
499 + 31597003 = 31597502
613 + 31596889 = 31597502

Showing the first eight; more decompositions exist.
