Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521058, here are decompositions:

7 + 521051 = 521058
11 + 521047 = 521058
17 + 521041 = 521058
19 + 521039 = 521058
37 + 521021 = 521058
89 + 520969 = 521058
101 + 520957 = 521058
137 + 520921 = 521058

Showing the first eight; more decompositions exist.
