Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664986, here are decompositions:

7 + 8664979 = 8664986
37 + 8664949 = 8664986
79 + 8664907 = 8664986
139 + 8664847 = 8664986
199 + 8664787 = 8664986
229 + 8664757 = 8664986
373 + 8664613 = 8664986
433 + 8664553 = 8664986

Showing the first eight; more decompositions exist.
