Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530642, here are decompositions:

43 + 530599 = 530642
103 + 530539 = 530642
109 + 530533 = 530642
199 + 530443 = 530642
241 + 530401 = 530642
283 + 530359 = 530642
313 + 530329 = 530642
349 + 530293 = 530642

Showing the first eight; more decompositions exist.
