Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023668, here are decompositions:

67 + 1023601 = 1023668
97 + 1023571 = 1023668
127 + 1023541 = 1023668
181 + 1023487 = 1023668
277 + 1023391 = 1023668
307 + 1023361 = 1023668
367 + 1023301 = 1023668
379 + 1023289 = 1023668

Showing the first eight; more decompositions exist.
