Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732644, here are decompositions:

3 + 8732641 = 8732644
5 + 8732639 = 8732644
17 + 8732627 = 8732644
71 + 8732573 = 8732644
197 + 8732447 = 8732644
227 + 8732417 = 8732644
233 + 8732411 = 8732644
281 + 8732363 = 8732644

Showing the first eight; more decompositions exist.
