Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598868, here are decompositions:

5 + 31598863 = 31598868
11 + 31598857 = 31598868
29 + 31598839 = 31598868
79 + 31598789 = 31598868
89 + 31598779 = 31598868
97 + 31598771 = 31598868
151 + 31598717 = 31598868
167 + 31598701 = 31598868

Showing the first eight; more decompositions exist.
