Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055220, here are decompositions:

29 + 1055191 = 1055220
31 + 1055189 = 1055220
53 + 1055167 = 1055220
79 + 1055141 = 1055220
83 + 1055137 = 1055220
107 + 1055113 = 1055220
137 + 1055083 = 1055220
157 + 1055063 = 1055220

Showing the first eight; more decompositions exist.
