Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628364, here are decompositions:

11 + 31628353 = 31628364
13 + 31628351 = 31628364
23 + 31628341 = 31628364
37 + 31628327 = 31628364
73 + 31628291 = 31628364
191 + 31628173 = 31628364
193 + 31628171 = 31628364
197 + 31628167 = 31628364

Showing the first eight; more decompositions exist.
