Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598966, here are decompositions:

13 + 31598953 = 31598966
19 + 31598947 = 31598966
43 + 31598923 = 31598966
79 + 31598887 = 31598966
103 + 31598863 = 31598966
109 + 31598857 = 31598966
127 + 31598839 = 31598966
283 + 31598683 = 31598966

Showing the first eight; more decompositions exist.
