Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66822, here are decompositions:

13 + 66809 = 66822
31 + 66791 = 66822
59 + 66763 = 66822
71 + 66751 = 66822
73 + 66749 = 66822
83 + 66739 = 66822
89 + 66733 = 66822
101 + 66721 = 66822

Showing the first eight; more decompositions exist.
