Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598858, here are decompositions:

19 + 31598839 = 31598858
79 + 31598779 = 31598858
157 + 31598701 = 31598858
211 + 31598647 = 31598858
337 + 31598521 = 31598858
409 + 31598449 = 31598858
439 + 31598419 = 31598858
457 + 31598401 = 31598858

Showing the first eight; more decompositions exist.
