Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40812, here are decompositions:

11 + 40801 = 40812
41 + 40771 = 40812
53 + 40759 = 40812
61 + 40751 = 40812
73 + 40739 = 40812
103 + 40709 = 40812
113 + 40699 = 40812
173 + 40639 = 40812

Showing the first eight; more decompositions exist.
