Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549550, here are decompositions:

3 + 31549547 = 31549550
139 + 31549411 = 31549550
211 + 31549339 = 31549550
223 + 31549327 = 31549550
313 + 31549237 = 31549550
349 + 31549201 = 31549550
367 + 31549183 = 31549550
433 + 31549117 = 31549550

Showing the first eight; more decompositions exist.
