Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521070, here are decompositions:

7 + 521063 = 521070
19 + 521051 = 521070
23 + 521047 = 521070
29 + 521041 = 521070
31 + 521039 = 521070
47 + 521023 = 521070
61 + 521009 = 521070
89 + 520981 = 521070

Showing the first eight; more decompositions exist.
