Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027812, here are decompositions:

13 + 1027799 = 1027812
29 + 1027783 = 1027812
53 + 1027759 = 1027812
59 + 1027753 = 1027812
61 + 1027751 = 1027812
73 + 1027739 = 1027812
109 + 1027703 = 1027812
199 + 1027613 = 1027812

Showing the first eight; more decompositions exist.
