Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530228, here are decompositions:

19 + 530209 = 530228
31 + 530197 = 530228
211 + 530017 = 530228
229 + 529999 = 530228
241 + 529987 = 530228
271 + 529957 = 530228
409 + 529819 = 530228
421 + 529807 = 530228

Showing the first eight; more decompositions exist.
