Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20488, here are decompositions:

5 + 20483 = 20488
11 + 20477 = 20488
47 + 20441 = 20488
89 + 20399 = 20488
131 + 20357 = 20488
191 + 20297 = 20488
227 + 20261 = 20488
239 + 20249 = 20488

Showing the first eight; more decompositions exist.
