Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597792, here are decompositions:

29 + 31597763 = 31597792
53 + 31597739 = 31597792
71 + 31597721 = 31597792
179 + 31597613 = 31597792
251 + 31597541 = 31597792
509 + 31597283 = 31597792
593 + 31597199 = 31597792
641 + 31597151 = 31597792

Showing the first eight; more decompositions exist.
