Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520624, here are decompositions:

3 + 520621 = 520624
17 + 520607 = 520624
53 + 520571 = 520624
173 + 520451 = 520624
191 + 520433 = 520624
197 + 520427 = 520624
263 + 520361 = 520624
311 + 520313 = 520624

Showing the first eight; more decompositions exist.
