Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520130, here are decompositions:

7 + 520123 = 520130
19 + 520111 = 520130
67 + 520063 = 520130
109 + 520021 = 520130
199 + 519931 = 520130
211 + 519919 = 520130
223 + 519907 = 520130
241 + 519889 = 520130

Showing the first eight; more decompositions exist.
