Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20708, here are decompositions:

67 + 20641 = 20708
97 + 20611 = 20708
109 + 20599 = 20708
157 + 20551 = 20708
199 + 20509 = 20708
229 + 20479 = 20708
277 + 20431 = 20708
349 + 20359 = 20708

Showing the first eight; more decompositions exist.
