Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018958, here are decompositions:

79 + 1018879 = 1018958
151 + 1018807 = 1018958
181 + 1018777 = 1018958
229 + 1018729 = 1018958
307 + 1018651 = 1018958
337 + 1018621 = 1018958
487 + 1018471 = 1018958
547 + 1018411 = 1018958

Showing the first eight; more decompositions exist.
