Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522722, here are decompositions:

3 + 522719 = 522722
19 + 522703 = 522722
43 + 522679 = 522722
61 + 522661 = 522722
181 + 522541 = 522722
199 + 522523 = 522722
283 + 522439 = 522722
313 + 522409 = 522722

Showing the first eight; more decompositions exist.
