Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023856, here are decompositions:

5 + 1023851 = 1023856
17 + 1023839 = 1023856
23 + 1023833 = 1023856
137 + 1023719 = 1023856
389 + 1023467 = 1023856
443 + 1023413 = 1023856
467 + 1023389 = 1023856
503 + 1023353 = 1023856

Showing the first eight; more decompositions exist.
