Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618748, here are decompositions:

11 + 8618737 = 8618748
59 + 8618689 = 8618748
67 + 8618681 = 8618748
109 + 8618639 = 8618748
157 + 8618591 = 8618748
167 + 8618581 = 8618748
181 + 8618567 = 8618748
191 + 8618557 = 8618748

Showing the first eight; more decompositions exist.
