Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598386, here are decompositions:

5 + 31598381 = 31598386
23 + 31598363 = 31598386
59 + 31598327 = 31598386
107 + 31598279 = 31598386
173 + 31598213 = 31598386
353 + 31598033 = 31598386
359 + 31598027 = 31598386
389 + 31597997 = 31598386

Showing the first eight; more decompositions exist.
