Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051220, here are decompositions:

43 + 1051177 = 1051220
67 + 1051153 = 1051220
73 + 1051147 = 1051220
139 + 1051081 = 1051220
151 + 1051069 = 1051220
193 + 1051027 = 1051220
211 + 1051009 = 1051220
223 + 1050997 = 1051220

Showing the first eight; more decompositions exist.
