Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028146, here are decompositions:

5 + 1028141 = 1028146
17 + 1028129 = 1028146
29 + 1028117 = 1028146
47 + 1028099 = 1028146
83 + 1028063 = 1028146
263 + 1027883 = 1028146
293 + 1027853 = 1028146
347 + 1027799 = 1028146

Showing the first eight; more decompositions exist.
