Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027798, here are decompositions:

11 + 1027787 = 1027798
41 + 1027757 = 1027798
47 + 1027751 = 1027798
59 + 1027739 = 1027798
71 + 1027727 = 1027798
251 + 1027547 = 1027798
311 + 1027487 = 1027798
389 + 1027409 = 1027798

Showing the first eight; more decompositions exist.
