Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549292, here are decompositions:

109 + 31549183 = 31549292
193 + 31549099 = 31549292
211 + 31549081 = 31549292
241 + 31549051 = 31549292
283 + 31549009 = 31549292
331 + 31548961 = 31549292
421 + 31548871 = 31549292
673 + 31548619 = 31549292

Showing the first eight; more decompositions exist.
