Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599000, here are decompositions:

11 + 31598989 = 31599000
47 + 31598953 = 31599000
53 + 31598947 = 31599000
61 + 31598939 = 31599000
67 + 31598933 = 31599000
73 + 31598927 = 31599000
89 + 31598911 = 31599000
113 + 31598887 = 31599000

Showing the first eight; more decompositions exist.
