Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20536, here are decompositions:

3 + 20533 = 20536
29 + 20507 = 20536
53 + 20483 = 20536
59 + 20477 = 20536
137 + 20399 = 20536
167 + 20369 = 20536
179 + 20357 = 20536
239 + 20297 = 20536

Showing the first eight; more decompositions exist.
