Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494980, here are decompositions:

41 + 494939 = 494980
47 + 494933 = 494980
53 + 494927 = 494980
107 + 494873 = 494980
131 + 494849 = 494980
137 + 494843 = 494980
191 + 494789 = 494980
197 + 494783 = 494980

Showing the first eight; more decompositions exist.
