Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549594, here are decompositions:

3 + 31549591 = 31549594
5 + 31549589 = 31549594
47 + 31549547 = 31549594
191 + 31549403 = 31549594
257 + 31549337 = 31549594
317 + 31549277 = 31549594
353 + 31549241 = 31549594
641 + 31548953 = 31549594

Showing the first eight; more decompositions exist.
