Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678268, here are decompositions:

  • 31 + 8678237 = 8678268
  • 89 + 8678179 = 8678268
  • 107 + 8678161 = 8678268
  • 127 + 8678141 = 8678268
  • 139 + 8678129 = 8678268
  • 199 + 8678069 = 8678268
  • 211 + 8678057 = 8678268
  • 229 + 8678039 = 8678268

Showing the first eight; more decompositions exist.
