Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498638, here are decompositions:

61 + 498577 = 498638
199 + 498439 = 498638
229 + 498409 = 498638
241 + 498397 = 498638
271 + 498367 = 498638
277 + 498361 = 498638
307 + 498331 = 498638
337 + 498301 = 498638

Showing the first eight; more decompositions exist.
