Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549346, here are decompositions:

7 + 31549339 = 31549346
19 + 31549327 = 31549346
109 + 31549237 = 31549346
139 + 31549207 = 31549346
163 + 31549183 = 31549346
229 + 31549117 = 31549346
307 + 31549039 = 31549346
337 + 31549009 = 31549346

Showing the first eight; more decompositions exist.
