Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654320, here are decompositions:

71 + 8654249 = 8654320
83 + 8654237 = 8654320
89 + 8654231 = 8654320
137 + 8654183 = 8654320
149 + 8654171 = 8654320
173 + 8654147 = 8654320
197 + 8654123 = 8654320
263 + 8654057 = 8654320

Showing the first eight; more decompositions exist.
