Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028980, here are decompositions:

11 + 1028969 = 1028980
23 + 1028957 = 1028980
41 + 1028939 = 1028980
107 + 1028873 = 1028980
137 + 1028843 = 1028980
233 + 1028747 = 1028980
311 + 1028669 = 1028980
317 + 1028663 = 1028980

Showing the first eight; more decompositions exist.
