Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549338, here are decompositions:

11 + 31549327 = 31549338
61 + 31549277 = 31549338
97 + 31549241 = 31549338
101 + 31549237 = 31549338
131 + 31549207 = 31549338
137 + 31549201 = 31549338
157 + 31549181 = 31549338
239 + 31549099 = 31549338

Showing the first eight; more decompositions exist.
