Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045858, here are decompositions:

17 + 1045841 = 1045858
29 + 1045829 = 1045858
59 + 1045799 = 1045858
131 + 1045727 = 1045858
167 + 1045691 = 1045858
179 + 1045679 = 1045858
251 + 1045607 = 1045858
311 + 1045547 = 1045858

Showing the first eight; more decompositions exist.
