Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598346, here are decompositions:

19 + 31598327 = 31598346
47 + 31598299 = 31598346
67 + 31598279 = 31598346
79 + 31598267 = 31598346
107 + 31598239 = 31598346
167 + 31598179 = 31598346
313 + 31598033 = 31598346
317 + 31598029 = 31598346

Showing the first eight; more decompositions exist.
