Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549236, here are decompositions:

29 + 31549207 = 31549236
53 + 31549183 = 31549236
137 + 31549099 = 31549236
149 + 31549087 = 31549236
193 + 31549043 = 31549236
197 + 31549039 = 31549236
227 + 31549009 = 31549236
239 + 31548997 = 31549236

Showing the first eight; more decompositions exist.
