Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026790, here are decompositions:

29 + 1026761 = 1026790
113 + 1026677 = 1026790
197 + 1026593 = 1026790
227 + 1026563 = 1026790
269 + 1026521 = 1026790
311 + 1026479 = 1026790
383 + 1026407 = 1026790
389 + 1026401 = 1026790

Showing the first eight; more decompositions exist.
