Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598356, here are decompositions:

3 + 31598353 = 31598356
29 + 31598327 = 31598356
89 + 31598267 = 31598356
347 + 31598009 = 31598356
359 + 31597997 = 31598356
443 + 31597913 = 31598356
479 + 31597877 = 31598356
563 + 31597793 = 31598356

Showing the first eight; more decompositions exist.
