Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488516, here are decompositions:

3 + 488513 = 488516
13 + 488503 = 488516
43 + 488473 = 488516
97 + 488419 = 488516
109 + 488407 = 488516
163 + 488353 = 488516
199 + 488317 = 488516
229 + 488287 = 488516

Showing the first eight; more decompositions exist.
