Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20228, here are decompositions:

67 + 20161 = 20228
79 + 20149 = 20228
127 + 20101 = 20228
139 + 20089 = 20228
157 + 20071 = 20228
181 + 20047 = 20228
199 + 20029 = 20228
337 + 19891 = 20228

Showing the first eight; more decompositions exist.
