Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597624, here are decompositions:

11 + 31597613 = 31597624
53 + 31597571 = 31597624
83 + 31597541 = 31597624
131 + 31597493 = 31597624
257 + 31597367 = 31597624
503 + 31597121 = 31597624
593 + 31597031 = 31597624
647 + 31596977 = 31597624

Showing the first eight; more decompositions exist.
