Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598326, here are decompositions:

5 + 31598321 = 31598326
47 + 31598279 = 31598326
59 + 31598267 = 31598326
113 + 31598213 = 31598326
269 + 31598057 = 31598326
293 + 31598033 = 31598326
317 + 31598009 = 31598326
449 + 31597877 = 31598326

Showing the first eight; more decompositions exist.
