Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006812, here are decompositions:

13 + 1006799 = 1006812
29 + 1006783 = 1006812
31 + 1006781 = 1006812
43 + 1006769 = 1006812
61 + 1006751 = 1006812
73 + 1006739 = 1006812
101 + 1006711 = 1006812
179 + 1006633 = 1006812

Showing the first eight; more decompositions exist.
