Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023566, here are decompositions:

67 + 1023499 = 1023566
79 + 1023487 = 1023566
157 + 1023409 = 1023566
199 + 1023367 = 1023566
277 + 1023289 = 1023566
307 + 1023259 = 1023566
337 + 1023229 = 1023566
367 + 1023199 = 1023566

Showing the first eight; more decompositions exist.
