Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597532, here are decompositions:

61 + 31597471 = 31597532
79 + 31597453 = 31597532
271 + 31597261 = 31597532
433 + 31597099 = 31597532
541 + 31596991 = 31597532
619 + 31596913 = 31597532
643 + 31596889 = 31597532
739 + 31596793 = 31597532

Showing the first eight; more decompositions exist.
