Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597628, here are decompositions:

79 + 31597549 = 31597628
157 + 31597471 = 31597628
211 + 31597417 = 31597628
367 + 31597261 = 31597628
397 + 31597231 = 31597628
499 + 31597129 = 31597628
547 + 31597081 = 31597628
577 + 31597051 = 31597628

Showing the first eight; more decompositions exist.
