Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520372, here are decompositions:

3 + 520369 = 520372
11 + 520361 = 520372
23 + 520349 = 520372
59 + 520313 = 520372
131 + 520241 = 520372
179 + 520193 = 520372
269 + 520103 = 520372
353 + 520019 = 520372

Showing the first eight; more decompositions exist.
