Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664372, here are decompositions:

5 + 8664367 = 8664372
43 + 8664329 = 8664372
61 + 8664311 = 8664372
113 + 8664259 = 8664372
149 + 8664223 = 8664372
179 + 8664193 = 8664372
191 + 8664181 = 8664372
263 + 8664109 = 8664372

Showing the first eight; more decompositions exist.
