Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494902, here are decompositions:

3 + 494899 = 494902
29 + 494873 = 494902
53 + 494849 = 494902
59 + 494843 = 494902
113 + 494789 = 494902
179 + 494723 = 494902
251 + 494651 = 494902
263 + 494639 = 494902

Showing the first eight; more decompositions exist.
