Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521152, here are decompositions:

89 + 521063 = 521152
101 + 521051 = 521152
113 + 521039 = 521152
131 + 521021 = 521152
239 + 520913 = 521152
263 + 520889 = 521152
311 + 520841 = 521152
389 + 520763 = 521152

Showing the first eight; more decompositions exist.
