Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599074, here are decompositions:

127 + 31598947 = 31599074
151 + 31598923 = 31599074
163 + 31598911 = 31599074
211 + 31598863 = 31599074
373 + 31598701 = 31599074
673 + 31598401 = 31599074
883 + 31598191 = 31599074
937 + 31598137 = 31599074

Showing the first eight; more decompositions exist.
