Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530280, here are decompositions:

13 + 530267 = 530280
19 + 530261 = 530280
29 + 530251 = 530280
31 + 530249 = 530280
43 + 530237 = 530280
53 + 530227 = 530280
71 + 530209 = 530280
83 + 530197 = 530280

Showing the first eight; more decompositions exist.
