Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026838, here are decompositions:

5 + 1026833 = 1026838
47 + 1026791 = 1026838
251 + 1026587 = 1026838
257 + 1026581 = 1026838
317 + 1026521 = 1026838
359 + 1026479 = 1026838
389 + 1026449 = 1026838
431 + 1026407 = 1026838

Showing the first eight; more decompositions exist.
