Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647898, here are decompositions:

  • 19 + 8647879 = 8647898
  • 79 + 8647819 = 8647898
  • 97 + 8647801 = 8647898
  • 139 + 8647759 = 8647898
  • 199 + 8647699 = 8647898
  • 241 + 8647657 = 8647898
  • 331 + 8647567 = 8647898
  • 367 + 8647531 = 8647898

Showing the first eight; more decompositions exist.
