Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520684, here are decompositions:

5 + 520679 = 520684
53 + 520631 = 520684
113 + 520571 = 520684
137 + 520547 = 520684
233 + 520451 = 520684
251 + 520433 = 520684
257 + 520427 = 520684
443 + 520241 = 520684

Showing the first eight; more decompositions exist.
