Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028542, here are decompositions:

71 + 1028471 = 1028542
131 + 1028411 = 1028542
149 + 1028393 = 1028542
233 + 1028309 = 1028542
239 + 1028303 = 1028542
269 + 1028273 = 1028542
311 + 1028231 = 1028542
353 + 1028189 = 1028542

Showing the first eight; more decompositions exist.
