Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522750, here are decompositions:

13 + 522737 = 522750
31 + 522719 = 522750
43 + 522707 = 522750
47 + 522703 = 522750
61 + 522689 = 522750
71 + 522679 = 522750
73 + 522677 = 522750
89 + 522661 = 522750

Showing the first eight; more decompositions exist.
