Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045918, here are decompositions:

11 + 1045907 = 1045918
59 + 1045859 = 1045918
89 + 1045829 = 1045918
179 + 1045739 = 1045918
191 + 1045727 = 1045918
227 + 1045691 = 1045918
239 + 1045679 = 1045918
311 + 1045607 = 1045918

Showing the first eight; more decompositions exist.
