Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660432, here are decompositions:

13 + 8660419 = 8660432
19 + 8660413 = 8660432
31 + 8660401 = 8660432
163 + 8660269 = 8660432
199 + 8660233 = 8660432
211 + 8660221 = 8660432
229 + 8660203 = 8660432
271 + 8660161 = 8660432

Showing the first eight; more decompositions exist.
