Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530660, here are decompositions:

7 + 530653 = 530660
19 + 530641 = 530660
61 + 530599 = 530660
127 + 530533 = 530660
271 + 530389 = 530660
307 + 530353 = 530660
331 + 530329 = 530660
367 + 530293 = 530660

Showing the first eight; more decompositions exist.
