Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022928, here are decompositions:

17 + 1022911 = 1022928
29 + 1022899 = 1022928
37 + 1022891 = 1022928
47 + 1022881 = 1022928
59 + 1022869 = 1022928
79 + 1022849 = 1022928
107 + 1022821 = 1022928
131 + 1022797 = 1022928

Showing the first eight; more decompositions exist.
