Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717138, here are decompositions:

7 + 8717131 = 8717138
19 + 8717119 = 8717138
97 + 8717041 = 8717138
127 + 8717011 = 8717138
139 + 8716999 = 8717138
181 + 8716957 = 8717138
277 + 8716861 = 8717138
379 + 8716759 = 8717138

Showing the first eight; more decompositions exist.
