Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028508, here are decompositions:

29 + 1028479 = 1028508
37 + 1028471 = 1028508
71 + 1028437 = 1028508
97 + 1028411 = 1028508
179 + 1028329 = 1028508
181 + 1028327 = 1028508
191 + 1028317 = 1028508
199 + 1028309 = 1028508

Showing the first eight; more decompositions exist.
