Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598924, here are decompositions:

13 + 31598911 = 31598924
37 + 31598887 = 31598924
61 + 31598863 = 31598924
67 + 31598857 = 31598924
223 + 31598701 = 31598924
241 + 31598683 = 31598924
277 + 31598647 = 31598924
523 + 31598401 = 31598924

Showing the first eight; more decompositions exist.
