Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045870, here are decompositions:

11 + 1045859 = 1045870
29 + 1045841 = 1045870
41 + 1045829 = 1045870
71 + 1045799 = 1045870
107 + 1045763 = 1045870
131 + 1045739 = 1045870
179 + 1045691 = 1045870
191 + 1045679 = 1045870

Showing the first eight; more decompositions exist.
