Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007812, here are decompositions:

5 + 1007807 = 1007812
11 + 1007801 = 1007812
23 + 1007789 = 1007812
41 + 1007771 = 1007812
53 + 1007759 = 1007812
59 + 1007753 = 1007812
83 + 1007729 = 1007812
89 + 1007723 = 1007812

Showing the first eight; more decompositions exist.
