Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018346, here are decompositions:

37 + 1018309 = 1018346
139 + 1018207 = 1018346
223 + 1018123 = 1018346
349 + 1017997 = 1018346
457 + 1017889 = 1018346
487 + 1017859 = 1018346
499 + 1017847 = 1018346
547 + 1017799 = 1018346

Showing the first eight; more decompositions exist.
