Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494740, here are decompositions:

3 + 494737 = 494740
17 + 494723 = 494740
41 + 494699 = 494740
47 + 494693 = 494740
53 + 494687 = 494740
89 + 494651 = 494740
101 + 494639 = 494740
131 + 494609 = 494740

Showing the first eight; more decompositions exist.
