Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520450, here are decompositions:

3 + 520447 = 520450
17 + 520433 = 520450
23 + 520427 = 520450
41 + 520409 = 520450
71 + 520379 = 520450
89 + 520361 = 520450
101 + 520349 = 520450
137 + 520313 = 520450

Showing the first eight; more decompositions exist.
