Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19922, here are decompositions:

3 + 19919 = 19922
31 + 19891 = 19922
61 + 19861 = 19922
79 + 19843 = 19922
103 + 19819 = 19922
109 + 19813 = 19922
163 + 19759 = 19922
223 + 19699 = 19922

Showing the first eight; more decompositions exist.
