Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530648, here are decompositions:

7 + 530641 = 530648
109 + 530539 = 530648
397 + 530251 = 530648
421 + 530227 = 530648
439 + 530209 = 530648
607 + 530041 = 530648
631 + 530017 = 530648
661 + 529987 = 530648

Showing the first eight; more decompositions exist.
