Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520830, here are decompositions:

17 + 520813 = 520830
43 + 520787 = 520830
67 + 520763 = 520830
71 + 520759 = 520830
83 + 520747 = 520830
109 + 520721 = 520830
113 + 520717 = 520830
127 + 520703 = 520830

Showing the first eight; more decompositions exist.
