Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023786, here are decompositions:

17 + 1023769 = 1023786
53 + 1023733 = 1023786
67 + 1023719 = 1023786
89 + 1023697 = 1023786
229 + 1023557 = 1023786
367 + 1023419 = 1023786
373 + 1023413 = 1023786
397 + 1023389 = 1023786

Showing the first eight; more decompositions exist.
