Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664398, here are decompositions:

31 + 8664367 = 8664398
139 + 8664259 = 8664398
241 + 8664157 = 8664398
439 + 8663959 = 8664398
499 + 8663899 = 8664398
571 + 8663827 = 8664398
577 + 8663821 = 8664398
601 + 8663797 = 8664398

Showing the first eight; more decompositions exist.
