Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488920, here are decompositions:

11 + 488909 = 488920
23 + 488897 = 488920
41 + 488879 = 488920
59 + 488861 = 488920
191 + 488729 = 488920
197 + 488723 = 488920
233 + 488687 = 488920
269 + 488651 = 488920

Showing the first eight; more decompositions exist.
