Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051148, here are decompositions:

67 + 1051081 = 1051148
79 + 1051069 = 1051148
97 + 1051051 = 1051148
139 + 1051009 = 1051148
151 + 1050997 = 1051148
199 + 1050949 = 1051148
331 + 1050817 = 1051148
337 + 1050811 = 1051148

Showing the first eight; more decompositions exist.
