Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21752, here are decompositions:

13 + 21739 = 21752
79 + 21673 = 21752
103 + 21649 = 21752
139 + 21613 = 21752
151 + 21601 = 21752
163 + 21589 = 21752
193 + 21559 = 21752
223 + 21529 = 21752

Showing the first eight; more decompositions exist.
