Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8652644, here are decompositions:

3 + 8652641 = 8652644
31 + 8652613 = 8652644
43 + 8652601 = 8652644
73 + 8652571 = 8652644
151 + 8652493 = 8652644
211 + 8652433 = 8652644
241 + 8652403 = 8652644
271 + 8652373 = 8652644

Showing the first eight; more decompositions exist.
