Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051278, here are decompositions:

31 + 1051247 = 1051278
97 + 1051181 = 1051278
101 + 1051177 = 1051278
127 + 1051151 = 1051278
131 + 1051147 = 1051278
139 + 1051139 = 1051278
197 + 1051081 = 1051278
199 + 1051079 = 1051278

Showing the first eight; more decompositions exist.
