Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20368, here are decompositions:

11 + 20357 = 20368
41 + 20327 = 20368
71 + 20297 = 20368
107 + 20261 = 20368
137 + 20231 = 20368
149 + 20219 = 20368
167 + 20201 = 20368
191 + 20177 = 20368

Showing the first eight; more decompositions exist.
