Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501722, here are decompositions:

3 + 501719 = 501722
19 + 501703 = 501722
31 + 501691 = 501722
211 + 501511 = 501722
229 + 501493 = 501722
271 + 501451 = 501722
313 + 501409 = 501722
379 + 501343 = 501722

Showing the first eight; more decompositions exist.
