Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055180, here are decompositions:

13 + 1055167 = 1055180
37 + 1055143 = 1055180
43 + 1055137 = 1055180
67 + 1055113 = 1055180
97 + 1055083 = 1055180
103 + 1055077 = 1055180
163 + 1055017 = 1055180
223 + 1054957 = 1055180

Showing the first eight; more decompositions exist.
