Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719398, here are decompositions:

7 + 8719391 = 8719398
19 + 8719379 = 8719398
31 + 8719367 = 8719398
71 + 8719327 = 8719398
97 + 8719301 = 8719398
109 + 8719289 = 8719398
137 + 8719261 = 8719398
179 + 8719219 = 8719398

Showing the first eight; more decompositions exist.
