Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717382, here are decompositions:

29 + 8717353 = 8717382
41 + 8717341 = 8717382
53 + 8717329 = 8717382
59 + 8717323 = 8717382
109 + 8717273 = 8717382
181 + 8717201 = 8717382
211 + 8717171 = 8717382
251 + 8717131 = 8717382

Showing the first eight; more decompositions exist.
