Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488686, here are decompositions:

47 + 488639 = 488686
53 + 488633 = 488686
59 + 488627 = 488686
83 + 488603 = 488686
113 + 488573 = 488686
173 + 488513 = 488686
227 + 488459 = 488686
269 + 488417 = 488686

Showing the first eight; more decompositions exist.
