Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549010, here are decompositions:

13 + 31548997 = 31549010
139 + 31548871 = 31549010
193 + 31548817 = 31549010
271 + 31548739 = 31549010
277 + 31548733 = 31549010
313 + 31548697 = 31549010
397 + 31548613 = 31549010
433 + 31548577 = 31549010

Showing the first eight; more decompositions exist.
