Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22812, here are decompositions:

5 + 22807 = 22812
29 + 22783 = 22812
43 + 22769 = 22812
61 + 22751 = 22812
71 + 22741 = 22812
73 + 22739 = 22812
103 + 22709 = 22812
113 + 22699 = 22812

Showing the first eight; more decompositions exist.
