Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027864, here are decompositions:

11 + 1027853 = 1027864
23 + 1027841 = 1027864
107 + 1027757 = 1027864
113 + 1027751 = 1027864
137 + 1027727 = 1027864
251 + 1027613 = 1027864
317 + 1027547 = 1027864
443 + 1027421 = 1027864

Showing the first eight; more decompositions exist.
