Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726644, here are decompositions:

11 + 8726633 = 8726644
71 + 8726573 = 8726644
137 + 8726507 = 8726644
197 + 8726447 = 8726644
263 + 8726381 = 8726644
281 + 8726363 = 8726644
293 + 8726351 = 8726644
401 + 8726243 = 8726644

Showing the first eight; more decompositions exist.
