Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521002, here are decompositions:

59 + 520943 = 521002
89 + 520913 = 521002
113 + 520889 = 521002
149 + 520853 = 521002
239 + 520763 = 521002
281 + 520721 = 521002
311 + 520691 = 521002
353 + 520649 = 521002

Showing the first eight; more decompositions exist.
