Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664380, here are decompositions:

3 + 8664377 = 8664380
13 + 8664367 = 8664380
157 + 8664223 = 8664380
199 + 8664181 = 8664380
223 + 8664157 = 8664380
271 + 8664109 = 8664380
337 + 8664043 = 8664380
421 + 8663959 = 8664380

Showing the first eight; more decompositions exist.
