Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549522, here are decompositions:

23 + 31549499 = 31549522
71 + 31549451 = 31549522
83 + 31549439 = 31549522
131 + 31549391 = 31549522
149 + 31549373 = 31549522
281 + 31549241 = 31549522
479 + 31549043 = 31549522
503 + 31549019 = 31549522

Showing the first eight; more decompositions exist.
