Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461934, here are decompositions:

11 + 31461923 = 31461934
41 + 31461893 = 31461934
47 + 31461887 = 31461934
83 + 31461851 = 31461934
173 + 31461761 = 31461934
191 + 31461743 = 31461934
197 + 31461737 = 31461934
281 + 31461653 = 31461934

Showing the first eight; more decompositions exist.
