Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522780, here are decompositions:

17 + 522763 = 522780
19 + 522761 = 522780
23 + 522757 = 522780
31 + 522749 = 522780
43 + 522737 = 522780
61 + 522719 = 522780
73 + 522707 = 522780
101 + 522679 = 522780

Showing the first eight; more decompositions exist.
