Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664690, here are decompositions:

19 + 8664671 = 8664690
29 + 8664661 = 8664690
109 + 8664581 = 8664690
131 + 8664559 = 8664690
137 + 8664553 = 8664690
163 + 8664527 = 8664690
173 + 8664517 = 8664690
239 + 8664451 = 8664690

Showing the first eight; more decompositions exist.
