Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549548, here are decompositions:

97 + 31549451 = 31549548
109 + 31549439 = 31549548
137 + 31549411 = 31549548
157 + 31549391 = 31549548
167 + 31549381 = 31549548
211 + 31549337 = 31549548
271 + 31549277 = 31549548
307 + 31549241 = 31549548

Showing the first eight; more decompositions exist.
