Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665328, here are decompositions:

109 + 8665219 = 8665328
127 + 8665201 = 8665328
181 + 8665147 = 8665328
229 + 8665099 = 8665328
307 + 8665021 = 8665328
337 + 8664991 = 8665328
349 + 8664979 = 8665328
367 + 8664961 = 8665328

Showing the first eight; more decompositions exist.
