Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494988, here are decompositions:

29 + 494959 = 494988
61 + 494927 = 494988
71 + 494917 = 494988
89 + 494899 = 494988
139 + 494849 = 494988
199 + 494789 = 494988
227 + 494761 = 494988
229 + 494759 = 494988

Showing the first eight; more decompositions exist.
