Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026878, here are decompositions:

19 + 1026859 = 1026878
31 + 1026847 = 1026878
67 + 1026811 = 1026878
79 + 1026799 = 1026878
199 + 1026679 = 1026878
211 + 1026667 = 1026878
331 + 1026547 = 1026878
397 + 1026481 = 1026878

Showing the first eight; more decompositions exist.
