Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648386, here are decompositions:

  • 17 + 8648369 = 8648386
  • 53 + 8648333 = 8648386
  • 293 + 8648093 = 8648386
  • 353 + 8648033 = 8648386
  • 389 + 8647997 = 8648386
  • 419 + 8647967 = 8648386
  • 449 + 8647937 = 8648386
  • 563 + 8647823 = 8648386

Showing the first eight; more decompositions exist.
