Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027678, here are decompositions:

131 + 1027547 = 1027678
191 + 1027487 = 1027678
251 + 1027427 = 1027678
257 + 1027421 = 1027678
269 + 1027409 = 1027678
347 + 1027331 = 1027678
359 + 1027319 = 1027678
389 + 1027289 = 1027678

Showing the first eight; more decompositions exist.
