Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045838, here are decompositions:

19 + 1045819 = 1045838
37 + 1045801 = 1045838
109 + 1045729 = 1045838
331 + 1045507 = 1045838
601 + 1045237 = 1045838
709 + 1045129 = 1045838
727 + 1045111 = 1045838
757 + 1045081 = 1045838

Showing the first eight; more decompositions exist.
