Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488636, here are decompositions:

3 + 488633 = 488636
19 + 488617 = 488636
97 + 488539 = 488636
163 + 488473 = 488636
229 + 488407 = 488636
283 + 488353 = 488636
307 + 488329 = 488636
349 + 488287 = 488636

Showing the first eight; more decompositions exist.
