Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530388, here are decompositions:

29 + 530359 = 530388
59 + 530329 = 530388
109 + 530279 = 530388
127 + 530261 = 530388
137 + 530251 = 530388
139 + 530249 = 530388
151 + 530237 = 530388
179 + 530209 = 530388

Showing the first eight; more decompositions exist.
