Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494020, here are decompositions:

41 + 493979 = 494020
47 + 493973 = 494020
53 + 493967 = 494020
83 + 493937 = 494020
89 + 493931 = 494020
101 + 493919 = 494020
167 + 493853 = 494020
227 + 493793 = 494020

Showing the first eight; more decompositions exist.
