Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530740, here are decompositions:

29 + 530711 = 530740
47 + 530693 = 530740
71 + 530669 = 530740
131 + 530609 = 530740
137 + 530603 = 530740
173 + 530567 = 530740
191 + 530549 = 530740
227 + 530513 = 530740

Showing the first eight; more decompositions exist.
