Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023866, here are decompositions:

97 + 1023769 = 1023866
223 + 1023643 = 1023866
367 + 1023499 = 1023866
379 + 1023487 = 1023866
457 + 1023409 = 1023866
499 + 1023367 = 1023866
577 + 1023289 = 1023866
607 + 1023259 = 1023866

Showing the first eight; more decompositions exist.
