Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494784, here are decompositions:

23 + 494761 = 494784
41 + 494743 = 494784
47 + 494737 = 494784
53 + 494731 = 494784
61 + 494723 = 494784
71 + 494713 = 494784
97 + 494687 = 494784
107 + 494677 = 494784

Showing the first eight; more decompositions exist.
