Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018256, here are decompositions:

3 + 1018253 = 1018256
79 + 1018177 = 1018256
199 + 1018057 = 1018256
367 + 1017889 = 1018256
397 + 1017859 = 1018256
409 + 1017847 = 1018256
439 + 1017817 = 1018256
457 + 1017799 = 1018256

Showing the first eight; more decompositions exist.
