Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981048, here are decompositions:

11 + 981037 = 981048
31 + 981017 = 981048
37 + 981011 = 981048
127 + 980921 = 981048
137 + 980911 = 981048
139 + 980909 = 981048
149 + 980899 = 981048
151 + 980897 = 981048

Showing the first eight; more decompositions exist.
