Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549662, here are decompositions:

13 + 31549649 = 31549662
71 + 31549591 = 31549662
73 + 31549589 = 31549662
83 + 31549579 = 31549662
101 + 31549561 = 31549662
163 + 31549499 = 31549662
211 + 31549451 = 31549662
223 + 31549439 = 31549662

Showing the first eight; more decompositions exist.
