Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554794, here are decompositions:

3 + 31554791 = 31554794
127 + 31554667 = 31554794
157 + 31554637 = 31554794
163 + 31554631 = 31554794
181 + 31554613 = 31554794
211 + 31554583 = 31554794
223 + 31554571 = 31554794
277 + 31554517 = 31554794

Showing the first eight; more decompositions exist.
