Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513788, here are decompositions:

7 + 513781 = 513788
19 + 513769 = 513788
61 + 513727 = 513788
97 + 513691 = 513788
109 + 513679 = 513788
139 + 513649 = 513788
157 + 513631 = 513788
277 + 513511 = 513788

Showing the first eight; more decompositions exist.
