Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018460, here are decompositions:

13 + 1018447 = 1018460
31 + 1018429 = 1018460
103 + 1018357 = 1018460
151 + 1018309 = 1018460
283 + 1018177 = 1018460
337 + 1018123 = 1018460
439 + 1018021 = 1018460
463 + 1017997 = 1018460

Showing the first eight; more decompositions exist.
