Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971664, here are decompositions:

11 + 971653 = 971664
13 + 971651 = 971664
73 + 971591 = 971664
101 + 971563 = 971664
103 + 971561 = 971664
151 + 971513 = 971664
163 + 971501 = 971664
173 + 971491 = 971664

Showing the first eight; more decompositions exist.
