Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741866, here are decompositions:

5 + 8741861 = 8741866
53 + 8741813 = 8741866
113 + 8741753 = 8741866
167 + 8741699 = 8741866
179 + 8741687 = 8741866
227 + 8741639 = 8741866
257 + 8741609 = 8741866
503 + 8741363 = 8741866

Showing the first eight; more decompositions exist.
