Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488816, here are decompositions:

19 + 488797 = 488816
37 + 488779 = 488816
67 + 488749 = 488816
73 + 488743 = 488816
127 + 488689 = 488816
199 + 488617 = 488816
277 + 488539 = 488816
313 + 488503 = 488816

Showing the first eight; more decompositions exist.
