Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20716, here are decompositions:

23 + 20693 = 20716
53 + 20663 = 20716
89 + 20627 = 20716
167 + 20549 = 20716
173 + 20543 = 20716
233 + 20483 = 20716
239 + 20477 = 20716
317 + 20399 = 20716

Showing the first eight; more decompositions exist.
