Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520208, here are decompositions:

79 + 520129 = 520208
97 + 520111 = 520208
211 + 519997 = 520208
277 + 519931 = 520208
421 + 519787 = 520208
439 + 519769 = 520208
541 + 519667 = 520208
631 + 519577 = 520208

Showing the first eight; more decompositions exist.
