Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10812, here are decompositions:

13 + 10799 = 10812
23 + 10789 = 10812
31 + 10781 = 10812
41 + 10771 = 10812
59 + 10753 = 10812
73 + 10739 = 10812
79 + 10733 = 10812
83 + 10729 = 10812

Showing the first eight; more decompositions exist.
