Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055980, here are decompositions:

11 + 1055969 = 1055980
41 + 1055939 = 1055980
47 + 1055933 = 1055980
83 + 1055897 = 1055980
113 + 1055867 = 1055980
179 + 1055801 = 1055980
197 + 1055783 = 1055980
239 + 1055741 = 1055980

Showing the first eight; more decompositions exist.
