Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055920, here are decompositions:

3 + 1055917 = 1055920
23 + 1055897 = 1055920
53 + 1055867 = 1055920
137 + 1055783 = 1055920
149 + 1055771 = 1055920
179 + 1055741 = 1055920
311 + 1055609 = 1055920
317 + 1055603 = 1055920

Showing the first eight; more decompositions exist.
