Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028122, here are decompositions:

5 + 1028117 = 1028122
23 + 1028099 = 1028122
41 + 1028081 = 1028122
59 + 1028063 = 1028122
71 + 1028051 = 1028122
191 + 1027931 = 1028122
239 + 1027883 = 1028122
269 + 1027853 = 1028122

Showing the first eight; more decompositions exist.
