Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741878, here are decompositions:

11 + 8741867 = 8741878
17 + 8741861 = 8741878
137 + 8741741 = 8741878
179 + 8741699 = 8741878
191 + 8741687 = 8741878
239 + 8741639 = 8741878
269 + 8741609 = 8741878
419 + 8741459 = 8741878

Showing the first eight; more decompositions exist.
