Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597826, here are decompositions:

3 + 31597823 = 31597826
97 + 31597729 = 31597826
109 + 31597717 = 31597826
223 + 31597603 = 31597826
277 + 31597549 = 31597826
373 + 31597453 = 31597826
409 + 31597417 = 31597826
613 + 31597213 = 31597826

Showing the first eight; more decompositions exist.
