Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640276, here are decompositions:

13 + 8640263 = 8640276
17 + 8640259 = 8640276
79 + 8640197 = 8640276
89 + 8640187 = 8640276
107 + 8640169 = 8640276
167 + 8640109 = 8640276
263 + 8640013 = 8640276
353 + 8639923 = 8640276

Showing the first eight; more decompositions exist.
