Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530428, here are decompositions:

89 + 530339 = 530428
131 + 530297 = 530428
149 + 530279 = 530428
167 + 530261 = 530428
179 + 530249 = 530428
191 + 530237 = 530428
251 + 530177 = 530428
401 + 530027 = 530428

Showing the first eight; more decompositions exist.
