Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717472, here are decompositions:

79 + 8717393 = 8717472
83 + 8717389 = 8717472
131 + 8717341 = 8717472
149 + 8717323 = 8717472
199 + 8717273 = 8717472
233 + 8717239 = 8717472
271 + 8717201 = 8717472
349 + 8717123 = 8717472

Showing the first eight; more decompositions exist.
