Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678278, here are decompositions:

  • 41 + 8678237 = 8678278
  • 131 + 8678147 = 8678278
  • 137 + 8678141 = 8678278
  • 149 + 8678129 = 8678278
  • 197 + 8678081 = 8678278
  • 227 + 8678051 = 8678278
  • 239 + 8678039 = 8678278
  • 251 + 8678027 = 8678278

Showing the first eight; more decompositions exist.
