Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045998, here are decompositions:

11 + 1045987 = 1045998
17 + 1045981 = 1045998
139 + 1045859 = 1045998
157 + 1045841 = 1045998
179 + 1045819 = 1045998
197 + 1045801 = 1045998
199 + 1045799 = 1045998
269 + 1045729 = 1045998

Showing the first eight; more decompositions exist.
