Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597426, here are decompositions:

59 + 31597367 = 31597426
89 + 31597337 = 31597426
173 + 31597253 = 31597426
227 + 31597199 = 31597426
383 + 31597043 = 31597426
449 + 31596977 = 31597426
503 + 31596923 = 31597426
569 + 31596857 = 31597426

Showing the first eight; more decompositions exist.
