Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631904, here are decompositions:

5 + 8631899 = 8631904
11 + 8631893 = 8631904
23 + 8631881 = 8631904
53 + 8631851 = 8631904
101 + 8631803 = 8631904
167 + 8631737 = 8631904
191 + 8631713 = 8631904
293 + 8631611 = 8631904

Showing the first eight; more decompositions exist.
