Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027690, here are decompositions:

3 + 1027687 = 1027690
11 + 1027679 = 1027690
47 + 1027643 = 1027690
197 + 1027493 = 1027690
263 + 1027427 = 1027690
269 + 1027421 = 1027690
281 + 1027409 = 1027690
359 + 1027331 = 1027690

Showing the first eight; more decompositions exist.
