Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664928, here are decompositions:

59 + 8664869 = 8664928
71 + 8664857 = 8664928
137 + 8664791 = 8664928
197 + 8664731 = 8664928
227 + 8664701 = 8664928
257 + 8664671 = 8664928
347 + 8664581 = 8664928
401 + 8664527 = 8664928

Showing the first eight; more decompositions exist.
