Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488556, here are decompositions:

17 + 488539 = 488556
43 + 488513 = 488556
53 + 488503 = 488556
83 + 488473 = 488556
97 + 488459 = 488556
137 + 488419 = 488556
139 + 488417 = 488556
149 + 488407 = 488556

Showing the first eight; more decompositions exist.
