Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529722, here are decompositions:

13 + 529709 = 529722
29 + 529693 = 529722
31 + 529691 = 529722
41 + 529681 = 529722
73 + 529649 = 529722
103 + 529619 = 529722
191 + 529531 = 529722
233 + 529489 = 529722

Showing the first eight; more decompositions exist.
