Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717384, here are decompositions:

31 + 8717353 = 8717384
43 + 8717341 = 8717384
61 + 8717323 = 8717384
97 + 8717287 = 8717384
271 + 8717113 = 8717384
373 + 8717011 = 8717384
523 + 8716861 = 8717384
541 + 8716843 = 8717384

Showing the first eight; more decompositions exist.
