Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521024, here are decompositions:

3 + 521021 = 521024
43 + 520981 = 521024
61 + 520963 = 521024
67 + 520957 = 521024
103 + 520921 = 521024
157 + 520867 = 521024
211 + 520813 = 521024
277 + 520747 = 521024

Showing the first eight; more decompositions exist.
