Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658472, here are decompositions:

3 + 8658469 = 8658472
41 + 8658431 = 8658472
59 + 8658413 = 8658472
89 + 8658383 = 8658472
101 + 8658371 = 8658472
149 + 8658323 = 8658472
239 + 8658233 = 8658472
269 + 8658203 = 8658472

Showing the first eight; more decompositions exist.
