Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494778, here are decompositions:

17 + 494761 = 494778
19 + 494759 = 494778
29 + 494749 = 494778
41 + 494737 = 494778
47 + 494731 = 494778
59 + 494719 = 494778
79 + 494699 = 494778
101 + 494677 = 494778

Showing the first eight; more decompositions exist.
