Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494722, here are decompositions:

3 + 494719 = 494722
23 + 494699 = 494722
29 + 494693 = 494722
71 + 494651 = 494722
83 + 494639 = 494722
101 + 494621 = 494722
113 + 494609 = 494722
131 + 494591 = 494722

Showing the first eight; more decompositions exist.
