Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028530, here are decompositions:

59 + 1028471 = 1028530
137 + 1028393 = 1028530
197 + 1028333 = 1028530
227 + 1028303 = 1028530
257 + 1028273 = 1028530
317 + 1028213 = 1028530
389 + 1028141 = 1028530
401 + 1028129 = 1028530

Showing the first eight; more decompositions exist.
