Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530722, here are decompositions:

11 + 530711 = 530722
29 + 530693 = 530722
53 + 530669 = 530722
113 + 530609 = 530722
173 + 530549 = 530722
191 + 530531 = 530722
293 + 530429 = 530722
383 + 530339 = 530722

Showing the first eight; more decompositions exist.
