Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678238, here are decompositions:

  • 59 + 8678179 = 8678238
  • 89 + 8678149 = 8678238
  • 97 + 8678141 = 8678238
  • 109 + 8678129 = 8678238
  • 157 + 8678081 = 8678238
  • 181 + 8678057 = 8678238
  • 199 + 8678039 = 8678238
  • 211 + 8678027 = 8678238

Showing the first eight; more decompositions exist.
