Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971180, here are decompositions:

3 + 971177 = 971180
31 + 971149 = 971180
37 + 971143 = 971180
103 + 971077 = 971180
127 + 971053 = 971180
151 + 971029 = 971180
181 + 970999 = 971180
193 + 970987 = 971180

Showing the first eight; more decompositions exist.
