Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599036, here are decompositions:

47 + 31598989 = 31599036
83 + 31598953 = 31599036
89 + 31598947 = 31599036
97 + 31598939 = 31599036
103 + 31598933 = 31599036
109 + 31598927 = 31599036
113 + 31598923 = 31599036
127 + 31598909 = 31599036

Showing the first eight; more decompositions exist.
