Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20502, here are decompositions:

19 + 20483 = 20502
23 + 20479 = 20502
59 + 20443 = 20502
61 + 20441 = 20502
71 + 20431 = 20502
103 + 20399 = 20502
109 + 20393 = 20502
113 + 20389 = 20502

Showing the first eight; more decompositions exist.
