Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717388, here are decompositions:

47 + 8717341 = 8717388
59 + 8717329 = 8717388
101 + 8717287 = 8717388
149 + 8717239 = 8717388
257 + 8717131 = 8717388
269 + 8717119 = 8717388
271 + 8717117 = 8717388
347 + 8717041 = 8717388

Showing the first eight; more decompositions exist.
