Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023456, here are decompositions:

37 + 1023419 = 1023456
43 + 1023413 = 1023456
47 + 1023409 = 1023456
67 + 1023389 = 1023456
89 + 1023367 = 1023456
103 + 1023353 = 1023456
127 + 1023329 = 1023456
139 + 1023317 = 1023456

Showing the first eight; more decompositions exist.
