Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051128, here are decompositions:

47 + 1051081 = 1051128
59 + 1051069 = 1051128
101 + 1051027 = 1051128
109 + 1051019 = 1051128
131 + 1050997 = 1051128
151 + 1050977 = 1051128
167 + 1050961 = 1051128
179 + 1050949 = 1051128

Showing the first eight; more decompositions exist.
