Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530644, here are decompositions:

3 + 530641 = 530644
41 + 530603 = 530644
47 + 530597 = 530644
113 + 530531 = 530644
131 + 530513 = 530644
137 + 530507 = 530644
197 + 530447 = 530644
251 + 530393 = 530644

Showing the first eight; more decompositions exist.
