Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549554, here are decompositions:

7 + 31549547 = 31549554
103 + 31549451 = 31549554
151 + 31549403 = 31549554
163 + 31549391 = 31549554
173 + 31549381 = 31549554
181 + 31549373 = 31549554
227 + 31549327 = 31549554
277 + 31549277 = 31549554

Showing the first eight; more decompositions exist.
