Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023656, here are decompositions:

3 + 1023653 = 1023656
13 + 1023643 = 1023656
79 + 1023577 = 1023656
157 + 1023499 = 1023656
367 + 1023289 = 1023656
379 + 1023277 = 1023656
397 + 1023259 = 1023656
457 + 1023199 = 1023656

Showing the first eight; more decompositions exist.
