Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549374, here are decompositions:

37 + 31549337 = 31549374
47 + 31549327 = 31549374
97 + 31549277 = 31549374
137 + 31549237 = 31549374
167 + 31549207 = 31549374
173 + 31549201 = 31549374
191 + 31549183 = 31549374
193 + 31549181 = 31549374

Showing the first eight; more decompositions exist.
