Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646320, here are decompositions:

3 + 8646317 = 8646320
43 + 8646277 = 8646320
61 + 8646259 = 8646320
73 + 8646247 = 8646320
97 + 8646223 = 8646320
139 + 8646181 = 8646320
157 + 8646163 = 8646320
349 + 8645971 = 8646320

Showing the first eight; more decompositions exist.
