Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598964, here are decompositions:

11 + 31598953 = 31598964
17 + 31598947 = 31598964
31 + 31598933 = 31598964
37 + 31598927 = 31598964
41 + 31598923 = 31598964
53 + 31598911 = 31598964
97 + 31598867 = 31598964
101 + 31598863 = 31598964

Showing the first eight; more decompositions exist.
