Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520432, here are decompositions:

5 + 520427 = 520432
23 + 520409 = 520432
53 + 520379 = 520432
71 + 520361 = 520432
83 + 520349 = 520432
191 + 520241 = 520432
239 + 520193 = 520432
281 + 520151 = 520432

Showing the first eight; more decompositions exist.
