Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599066, here are decompositions:

7 + 31599059 = 31599066
113 + 31598953 = 31599066
127 + 31598939 = 31599066
139 + 31598927 = 31599066
157 + 31598909 = 31599066
179 + 31598887 = 31599066
193 + 31598873 = 31599066
199 + 31598867 = 31599066

Showing the first eight; more decompositions exist.
