Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549958, here are decompositions:

61 + 31549897 = 31549958
67 + 31549891 = 31549958
79 + 31549879 = 31549958
157 + 31549801 = 31549958
229 + 31549729 = 31549958
241 + 31549717 = 31549958
367 + 31549591 = 31549958
379 + 31549579 = 31549958

Showing the first eight; more decompositions exist.
