Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549350, here are decompositions:

11 + 31549339 = 31549350
13 + 31549337 = 31549350
23 + 31549327 = 31549350
73 + 31549277 = 31549350
109 + 31549241 = 31549350
113 + 31549237 = 31549350
149 + 31549201 = 31549350
167 + 31549183 = 31549350

Showing the first eight; more decompositions exist.
