Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530386, here are decompositions:

47 + 530339 = 530386
53 + 530333 = 530386
83 + 530303 = 530386
89 + 530297 = 530386
107 + 530279 = 530386
137 + 530249 = 530386
149 + 530237 = 530386
257 + 530129 = 530386

Showing the first eight; more decompositions exist.
