Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494080, here are decompositions:

3 + 494077 = 494080
11 + 494069 = 494080
29 + 494051 = 494080
101 + 493979 = 494080
107 + 493973 = 494080
113 + 493967 = 494080
149 + 493931 = 494080
227 + 493853 = 494080

Showing the first eight; more decompositions exist.
