Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598994, here are decompositions:

5 + 31598989 = 31598994
41 + 31598953 = 31598994
47 + 31598947 = 31598994
61 + 31598933 = 31598994
67 + 31598927 = 31598994
71 + 31598923 = 31598994
83 + 31598911 = 31598994
107 + 31598887 = 31598994

Showing the first eight; more decompositions exist.
