Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509722, here are decompositions:

23 + 509699 = 509722
29 + 509693 = 509722
41 + 509681 = 509722
89 + 509633 = 509722
131 + 509591 = 509722
149 + 509573 = 509722
173 + 509549 = 509722
179 + 509543 = 509722

Showing the first eight; more decompositions exist.
