Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012858, here are decompositions:

29 + 1012829 = 1012858
47 + 1012811 = 1012858
89 + 1012769 = 1012858
107 + 1012751 = 1012858
137 + 1012721 = 1012858
167 + 1012691 = 1012858
179 + 1012679 = 1012858
227 + 1012631 = 1012858

Showing the first eight; more decompositions exist.
