Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520756, here are decompositions:

53 + 520703 = 520756
107 + 520649 = 520756
149 + 520607 = 520756
167 + 520589 = 520756
227 + 520529 = 520756
347 + 520409 = 520756
443 + 520313 = 520756
449 + 520307 = 520756

Showing the first eight; more decompositions exist.
