Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660644, here are decompositions:

101 + 8660543 = 8660644
107 + 8660537 = 8660644
137 + 8660507 = 8660644
257 + 8660387 = 8660644
263 + 8660381 = 8660644
347 + 8660297 = 8660644
353 + 8660291 = 8660644
467 + 8660177 = 8660644

Showing the first eight; more decompositions exist.
