Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592970, here are decompositions:

11 + 31592959 = 31592970
23 + 31592947 = 31592970
47 + 31592923 = 31592970
127 + 31592843 = 31592970
137 + 31592833 = 31592970
173 + 31592797 = 31592970
191 + 31592779 = 31592970
197 + 31592773 = 31592970

Showing the first eight; more decompositions exist.
