Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498040, here are decompositions:

41 + 497999 = 498040
47 + 497993 = 498040
71 + 497969 = 498040
83 + 497957 = 498040
167 + 497873 = 498040
173 + 497867 = 498040
227 + 497813 = 498040
239 + 497801 = 498040

Showing the first eight; more decompositions exist.
