Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971200, here are decompositions:

3 + 971197 = 971200
23 + 971177 = 971200
29 + 971171 = 971200
47 + 971153 = 971200
59 + 971141 = 971200
89 + 971111 = 971200
101 + 971099 = 971200
107 + 971093 = 971200

Showing the first eight; more decompositions exist.
