Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678928, here are decompositions:

  • 29 + 8678899 = 8678928
  • 107 + 8678821 = 8678928
  • 149 + 8678779 = 8678928
  • 151 + 8678777 = 8678928
  • 179 + 8678749 = 8678928
  • 227 + 8678701 = 8678928
  • 229 + 8678699 = 8678928
  • 257 + 8678671 = 8678928

Showing the first eight; more decompositions exist.
