Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631876, here are decompositions:

53 + 8631823 = 8631876
73 + 8631803 = 8631876
89 + 8631787 = 8631876
107 + 8631769 = 8631876
139 + 8631737 = 8631876
163 + 8631713 = 8631876
277 + 8631599 = 8631876
307 + 8631569 = 8631876

Showing the first eight; more decompositions exist.
