Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20330, here are decompositions:

3 + 20327 = 20330
7 + 20323 = 20330
43 + 20287 = 20330
61 + 20269 = 20330
97 + 20233 = 20330
157 + 20173 = 20330
181 + 20149 = 20330
223 + 20107 = 20330

Showing the first eight; more decompositions exist.
