Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644876, here are decompositions:

3 + 8644873 = 8644876
173 + 8644703 = 8644876
197 + 8644679 = 8644876
269 + 8644607 = 8644876
347 + 8644529 = 8644876
419 + 8644457 = 8644876
479 + 8644397 = 8644876
719 + 8644157 = 8644876

Showing the first eight; more decompositions exist.
