Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664566, here are decompositions:

7 + 8664559 = 8664566
13 + 8664553 = 8664566
19 + 8664547 = 8664566
37 + 8664529 = 8664566
139 + 8664427 = 8664566
199 + 8664367 = 8664566
307 + 8664259 = 8664566
373 + 8664193 = 8664566

Showing the first eight; more decompositions exist.
