Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549494, here are decompositions:

43 + 31549451 = 31549494
83 + 31549411 = 31549494
103 + 31549391 = 31549494
113 + 31549381 = 31549494
157 + 31549337 = 31549494
167 + 31549327 = 31549494
257 + 31549237 = 31549494
293 + 31549201 = 31549494

Showing the first eight; more decompositions exist.
