Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530398, here are decompositions:

5 + 530393 = 530398
59 + 530339 = 530398
101 + 530297 = 530398
131 + 530267 = 530398
137 + 530261 = 530398
149 + 530249 = 530398
269 + 530129 = 530398
311 + 530087 = 530398

Showing the first eight; more decompositions exist.
