Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20718, here are decompositions:

11 + 20707 = 20718
37 + 20681 = 20718
79 + 20639 = 20718
107 + 20611 = 20718
167 + 20551 = 20718
197 + 20521 = 20718
211 + 20507 = 20718
239 + 20479 = 20718

Showing the first eight; more decompositions exist.
