Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045876, here are decompositions:

17 + 1045859 = 1045876
47 + 1045829 = 1045876
113 + 1045763 = 1045876
137 + 1045739 = 1045876
149 + 1045727 = 1045876
197 + 1045679 = 1045876
233 + 1045643 = 1045876
269 + 1045607 = 1045876

Showing the first eight; more decompositions exist.
