Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598930, here are decompositions:

3 + 31598927 = 31598930
7 + 31598923 = 31598930
19 + 31598911 = 31598930
43 + 31598887 = 31598930
67 + 31598863 = 31598930
73 + 31598857 = 31598930
151 + 31598779 = 31598930
229 + 31598701 = 31598930

Showing the first eight; more decompositions exist.
