Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520086, here are decompositions:

13 + 520073 = 520086
19 + 520067 = 520086
23 + 520063 = 520086
43 + 520043 = 520086
67 + 520019 = 520086
89 + 519997 = 520086
97 + 519989 = 520086
139 + 519947 = 520086

Showing the first eight; more decompositions exist.
