Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045878, here are decompositions:

19 + 1045859 = 1045878
37 + 1045841 = 1045878
59 + 1045819 = 1045878
79 + 1045799 = 1045878
139 + 1045739 = 1045878
149 + 1045729 = 1045878
151 + 1045727 = 1045878
199 + 1045679 = 1045878

Showing the first eight; more decompositions exist.
