Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023188, here are decompositions:

109 + 1023079 = 1023188
151 + 1023037 = 1023188
211 + 1022977 = 1023188
277 + 1022911 = 1023188
307 + 1022881 = 1023188
367 + 1022821 = 1023188
487 + 1022701 = 1023188
499 + 1022689 = 1023188

Showing the first eight; more decompositions exist.
