Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600090, here are decompositions:

3 + 31600087 = 31600090
29 + 31600061 = 31600090
47 + 31600043 = 31600090
89 + 31600001 = 31600090
113 + 31599977 = 31600090
131 + 31599959 = 31600090
149 + 31599941 = 31600090
173 + 31599917 = 31600090

Showing the first eight; more decompositions exist.
