Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530378, here are decompositions:

19 + 530359 = 530378
127 + 530251 = 530378
151 + 530227 = 530378
181 + 530197 = 530378
241 + 530137 = 530378
337 + 530041 = 530378
379 + 529999 = 530378
397 + 529981 = 530378

Showing the first eight; more decompositions exist.
