Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598312, here are decompositions:

13 + 31598299 = 31598312
73 + 31598239 = 31598312
211 + 31598101 = 31598312
283 + 31598029 = 31598312
379 + 31597933 = 31598312
433 + 31597879 = 31598312
439 + 31597873 = 31598312
619 + 31597693 = 31598312

Showing the first eight; more decompositions exist.
