Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488656, here are decompositions:

5 + 488651 = 488656
17 + 488639 = 488656
23 + 488633 = 488656
29 + 488627 = 488656
53 + 488603 = 488656
83 + 488573 = 488656
89 + 488567 = 488656
197 + 488459 = 488656

Showing the first eight; more decompositions exist.
