Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520980, here are decompositions:

11 + 520969 = 520980
13 + 520967 = 520980
17 + 520963 = 520980
23 + 520957 = 520980
37 + 520943 = 520980
59 + 520921 = 520980
67 + 520913 = 520980
113 + 520867 = 520980

Showing the first eight; more decompositions exist.
