Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20726, here are decompositions:

7 + 20719 = 20726
19 + 20707 = 20726
127 + 20599 = 20726
163 + 20563 = 20726
193 + 20533 = 20726
283 + 20443 = 20726
337 + 20389 = 20726
367 + 20359 = 20726

Showing the first eight; more decompositions exist.
