Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549754, here are decompositions:

3 + 31549751 = 31549754
37 + 31549717 = 31549754
157 + 31549597 = 31549754
163 + 31549591 = 31549754
193 + 31549561 = 31549754
373 + 31549381 = 31549754
547 + 31549207 = 31549754
571 + 31549183 = 31549754

Showing the first eight; more decompositions exist.
