Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66800, here are decompositions:

3 + 66797 = 66800
37 + 66763 = 66800
61 + 66739 = 66800
67 + 66733 = 66800
79 + 66721 = 66800
103 + 66697 = 66800
157 + 66643 = 66800
199 + 66601 = 66800

Showing the first eight; more decompositions exist.
