Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530258, here are decompositions:

7 + 530251 = 530258
31 + 530227 = 530258
61 + 530197 = 530258
241 + 530017 = 530258
271 + 529987 = 530258
277 + 529981 = 530258
331 + 529927 = 530258
439 + 529819 = 530258

Showing the first eight; more decompositions exist.
