Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494028, here are decompositions:

5 + 494023 = 494028
61 + 493967 = 494028
89 + 493939 = 494028
97 + 493931 = 494028
109 + 493919 = 494028
131 + 493897 = 494028
151 + 493877 = 494028
211 + 493817 = 494028

Showing the first eight; more decompositions exist.
