Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549622, here are decompositions:

31 + 31549591 = 31549622
43 + 31549579 = 31549622
61 + 31549561 = 31549622
211 + 31549411 = 31549622
241 + 31549381 = 31549622
283 + 31549339 = 31549622
421 + 31549201 = 31549622
439 + 31549183 = 31549622

Showing the first eight; more decompositions exist.
