Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971640, here are decompositions:

71 + 971569 = 971640
79 + 971561 = 971640
127 + 971513 = 971640
139 + 971501 = 971640
149 + 971491 = 971640
157 + 971483 = 971640
167 + 971473 = 971640
199 + 971441 = 971640

Showing the first eight; more decompositions exist.
