Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522808, here are decompositions:

47 + 522761 = 522808
59 + 522749 = 522808
71 + 522737 = 522808
89 + 522719 = 522808
101 + 522707 = 522808
131 + 522677 = 522808
149 + 522659 = 522808
239 + 522569 = 522808

Showing the first eight; more decompositions exist.
