Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707286, here are decompositions:

  • 13 + 8707273 = 8707286
  • 67 + 8707219 = 8707286
  • 79 + 8707207 = 8707286
  • 97 + 8707189 = 8707286
  • 103 + 8707183 = 8707286
  • 127 + 8707159 = 8707286
  • 139 + 8707147 = 8707286
  • 163 + 8707123 = 8707286

Showing the first eight; more decompositions exist.
