Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971220, here are decompositions:

13 + 971207 = 971220
23 + 971197 = 971220
43 + 971177 = 971220
67 + 971153 = 971220
71 + 971149 = 971220
79 + 971141 = 971220
109 + 971111 = 971220
127 + 971093 = 971220

Showing the first eight; more decompositions exist.
