Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717438, here are decompositions:

97 + 8717341 = 8717438
109 + 8717329 = 8717438
151 + 8717287 = 8717438
199 + 8717239 = 8717438
307 + 8717131 = 8717438
397 + 8717041 = 8717438
439 + 8716999 = 8717438
547 + 8716891 = 8717438

Showing the first eight; more decompositions exist.
