Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740018, here are decompositions:

101 + 8739917 = 8740018
107 + 8739911 = 8740018
149 + 8739869 = 8740018
167 + 8739851 = 8740018
191 + 8739827 = 8740018
197 + 8739821 = 8740018
251 + 8739767 = 8740018
269 + 8739749 = 8740018

Showing the first eight; more decompositions exist.
