Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631844, here are decompositions:

41 + 8631803 = 8631844
101 + 8631743 = 8631844
107 + 8631737 = 8631844
131 + 8631713 = 8631844
227 + 8631617 = 8631844
233 + 8631611 = 8631844
311 + 8631533 = 8631844
443 + 8631401 = 8631844

Showing the first eight; more decompositions exist.
