Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971644, here are decompositions:

5 + 971639 = 971644
53 + 971591 = 971644
83 + 971561 = 971644
131 + 971513 = 971644
257 + 971387 = 971644
263 + 971381 = 971644
353 + 971291 = 971644
467 + 971177 = 971644

Showing the first eight; more decompositions exist.
