Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499788, here are decompositions:

7 + 499781 = 499788
41 + 499747 = 499788
59 + 499729 = 499788
71 + 499717 = 499788
97 + 499691 = 499788
101 + 499687 = 499788
109 + 499679 = 499788
127 + 499661 = 499788

Showing the first eight; more decompositions exist.
