Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598958, here are decompositions:

5 + 31598953 = 31598958
11 + 31598947 = 31598958
19 + 31598939 = 31598958
31 + 31598927 = 31598958
47 + 31598911 = 31598958
71 + 31598887 = 31598958
101 + 31598857 = 31598958
179 + 31598779 = 31598958

Showing the first eight; more decompositions exist.
