Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023720, here are decompositions:

23 + 1023697 = 1023720
67 + 1023653 = 1023720
149 + 1023571 = 1023720
163 + 1023557 = 1023720
179 + 1023541 = 1023720
199 + 1023521 = 1023720
233 + 1023487 = 1023720
307 + 1023413 = 1023720

Showing the first eight; more decompositions exist.
