Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018646, here are decompositions:

3 + 1018643 = 1018646
103 + 1018543 = 1018646
157 + 1018489 = 1018646
199 + 1018447 = 1018646
337 + 1018309 = 1018646
439 + 1018207 = 1018646
523 + 1018123 = 1018646
757 + 1017889 = 1018646

Showing the first eight; more decompositions exist.
