Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055178, here are decompositions:

11 + 1055167 = 1055178
37 + 1055141 = 1055178
41 + 1055137 = 1055178
101 + 1055077 = 1055178
139 + 1055039 = 1055178
227 + 1054951 = 1055178
251 + 1054927 = 1055178
269 + 1054909 = 1055178

Showing the first eight; more decompositions exist.
