Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020256, here are decompositions:

23 + 1020233 = 1020256
113 + 1020143 = 1020256
179 + 1020077 = 1020256
197 + 1020059 = 1020256
233 + 1020023 = 1020256
353 + 1019903 = 1020256
383 + 1019873 = 1020256
509 + 1019747 = 1020256

Showing the first eight; more decompositions exist.
