Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530802, here are decompositions:

5 + 530797 = 530802
29 + 530773 = 530802
59 + 530743 = 530802
61 + 530741 = 530802
71 + 530731 = 530802
89 + 530713 = 530802
101 + 530701 = 530802
109 + 530693 = 530802

Showing the first eight; more decompositions exist.
