Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82812, here are decompositions:

13 + 82799 = 82812
19 + 82793 = 82812
31 + 82781 = 82812
53 + 82759 = 82812
83 + 82729 = 82812
89 + 82723 = 82812
113 + 82699 = 82812
179 + 82633 = 82812

Showing the first eight; more decompositions exist.
