Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20544, here are decompositions:

11 + 20533 = 20544
23 + 20521 = 20544
37 + 20507 = 20544
61 + 20483 = 20544
67 + 20477 = 20544
101 + 20443 = 20544
103 + 20441 = 20544
113 + 20431 = 20544

Showing the first eight; more decompositions exist.
