Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658874, here are decompositions:

5 + 8658869 = 8658874
101 + 8658773 = 8658874
197 + 8658677 = 8658874
293 + 8658581 = 8658874
347 + 8658527 = 8658874
443 + 8658431 = 8658874
461 + 8658413 = 8658874
491 + 8658383 = 8658874

Showing the first eight; more decompositions exist.
