Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664140, here are decompositions:

31 + 8664109 = 8664140
97 + 8664043 = 8664140
103 + 8664037 = 8664140
181 + 8663959 = 8664140
241 + 8663899 = 8664140
271 + 8663869 = 8664140
313 + 8663827 = 8664140
337 + 8663803 = 8664140

Showing the first eight; more decompositions exist.
