Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522784, here are decompositions:

23 + 522761 = 522784
47 + 522737 = 522784
107 + 522677 = 522784
263 + 522521 = 522784
401 + 522383 = 522784
461 + 522323 = 522784
467 + 522317 = 522784
503 + 522281 = 522784

Showing the first eight; more decompositions exist.
