Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520788, here are decompositions:

29 + 520759 = 520788
41 + 520747 = 520788
67 + 520721 = 520788
71 + 520717 = 520788
89 + 520699 = 520788
97 + 520691 = 520788
109 + 520679 = 520788
139 + 520649 = 520788

Showing the first eight; more decompositions exist.
