Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530946, here are decompositions:

89 + 530857 = 530946
103 + 530843 = 530946
109 + 530837 = 530946
113 + 530833 = 530946
139 + 530807 = 530946
149 + 530797 = 530946
173 + 530773 = 530946
179 + 530767 = 530946

Showing the first eight; more decompositions exist.
