Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530784, here are decompositions:

11 + 530773 = 530784
17 + 530767 = 530784
31 + 530753 = 530784
41 + 530743 = 530784
43 + 530741 = 530784
53 + 530731 = 530784
71 + 530713 = 530784
73 + 530711 = 530784

Showing the first eight; more decompositions exist.
