Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023920, here are decompositions:

151 + 1023769 = 1023920
199 + 1023721 = 1023920
223 + 1023697 = 1023920
277 + 1023643 = 1023920
349 + 1023571 = 1023920
379 + 1023541 = 1023920
421 + 1023499 = 1023920
433 + 1023487 = 1023920

Showing the first eight; more decompositions exist.
