Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018418, here are decompositions:

7 + 1018411 = 1018418
61 + 1018357 = 1018418
109 + 1018309 = 1018418
127 + 1018291 = 1018418
211 + 1018207 = 1018418
241 + 1018177 = 1018418
397 + 1018021 = 1018418
421 + 1017997 = 1018418

Showing the first eight; more decompositions exist.
