Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664942, here are decompositions:

71 + 8664871 = 8664942
73 + 8664869 = 8664942
79 + 8664863 = 8664942
151 + 8664791 = 8664942
199 + 8664743 = 8664942
211 + 8664731 = 8664942
241 + 8664701 = 8664942
271 + 8664671 = 8664942

Showing the first eight; more decompositions exist.
