Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018928, here are decompositions:

139 + 1018789 = 1018928
151 + 1018777 = 1018928
199 + 1018729 = 1018928
277 + 1018651 = 1018928
307 + 1018621 = 1018928
439 + 1018489 = 1018928
457 + 1018471 = 1018928
499 + 1018429 = 1018928

Showing the first eight; more decompositions exist.
