Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027980, here are decompositions:

11 + 1027969 = 1027980
89 + 1027891 = 1027980
97 + 1027883 = 1027980
127 + 1027853 = 1027980
139 + 1027841 = 1027980
181 + 1027799 = 1027980
193 + 1027787 = 1027980
197 + 1027783 = 1027980

Showing the first eight; more decompositions exist.
