Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027886, here are decompositions:

3 + 1027883 = 1027886
103 + 1027783 = 1027886
109 + 1027777 = 1027886
127 + 1027759 = 1027886
193 + 1027693 = 1027886
199 + 1027687 = 1027886
337 + 1027549 = 1027886
367 + 1027519 = 1027886

Showing the first eight; more decompositions exist.
