Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549582, here are decompositions:

3 + 31549579 = 31549582
83 + 31549499 = 31549582
131 + 31549451 = 31549582
179 + 31549403 = 31549582
191 + 31549391 = 31549582
401 + 31549181 = 31549582
563 + 31549019 = 31549582
599 + 31548983 = 31549582

Showing the first eight; more decompositions exist.
