Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20482, here are decompositions:

3 + 20479 = 20482
5 + 20477 = 20482
41 + 20441 = 20482
71 + 20411 = 20482
83 + 20399 = 20482
89 + 20393 = 20482
113 + 20369 = 20482
149 + 20333 = 20482

Showing the first eight; more decompositions exist.
