Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522880, here are decompositions:

23 + 522857 = 522880
41 + 522839 = 522880
53 + 522827 = 522880
131 + 522749 = 522880
173 + 522707 = 522880
191 + 522689 = 522880
257 + 522623 = 522880
311 + 522569 = 522880

Showing the first eight; more decompositions exist.
