Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521502, here are decompositions:

5 + 521497 = 521502
11 + 521491 = 521502
19 + 521483 = 521502
31 + 521471 = 521502
73 + 521429 = 521502
101 + 521401 = 521502
103 + 521399 = 521502
109 + 521393 = 521502

Showing the first eight; more decompositions exist.
