Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20752, here are decompositions:

3 + 20749 = 20752
5 + 20747 = 20752
59 + 20693 = 20752
71 + 20681 = 20752
89 + 20663 = 20752
113 + 20639 = 20752
269 + 20483 = 20752
311 + 20441 = 20752

Showing the first eight; more decompositions exist.
