Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593970, here are decompositions:

11 + 31593959 = 31593970
17 + 31593953 = 31593970
101 + 31593869 = 31593970
131 + 31593839 = 31593970
137 + 31593833 = 31593970
173 + 31593797 = 31593970
251 + 31593719 = 31593970
281 + 31593689 = 31593970

Showing the first eight; more decompositions exist.
