Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20746, here are decompositions:

3 + 20743 = 20746
29 + 20717 = 20746
53 + 20693 = 20746
83 + 20663 = 20746
107 + 20639 = 20746
197 + 20549 = 20746
239 + 20507 = 20746
263 + 20483 = 20746

Showing the first eight; more decompositions exist.
