Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631846, here are decompositions:

23 + 8631823 = 8631846
43 + 8631803 = 8631846
59 + 8631787 = 8631846
103 + 8631743 = 8631846
109 + 8631737 = 8631846
173 + 8631673 = 8631846
229 + 8631617 = 8631846
277 + 8631569 = 8631846

Showing the first eight; more decompositions exist.
