Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494742, here are decompositions:

5 + 494737 = 494742
11 + 494731 = 494742
19 + 494723 = 494742
23 + 494719 = 494742
29 + 494713 = 494742
43 + 494699 = 494742
71 + 494671 = 494742
103 + 494639 = 494742

Showing the first eight; more decompositions exist.
