Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599090, here are decompositions:

31 + 31599059 = 31599090
101 + 31598989 = 31599090
137 + 31598953 = 31599090
151 + 31598939 = 31599090
157 + 31598933 = 31599090
163 + 31598927 = 31599090
167 + 31598923 = 31599090
179 + 31598911 = 31599090

Showing the first eight; more decompositions exist.
