Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530306, here are decompositions:

3 + 530303 = 530306
13 + 530293 = 530306
79 + 530227 = 530306
97 + 530209 = 530306
103 + 530203 = 530306
109 + 530197 = 530306
163 + 530143 = 530306
307 + 529999 = 530306

Showing the first eight; more decompositions exist.
