Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494978, here are decompositions:

19 + 494959 = 494978
61 + 494917 = 494978
79 + 494899 = 494978
229 + 494749 = 494978
241 + 494737 = 494978
307 + 494671 = 494978
331 + 494647 = 494978
439 + 494539 = 494978

Showing the first eight; more decompositions exist.
