Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704840, here are decompositions:

  • 3 + 8704837 = 8704840
  • 29 + 8704811 = 8704840
  • 83 + 8704757 = 8704840
  • 149 + 8704691 = 8704840
  • 227 + 8704613 = 8704840
  • 233 + 8704607 = 8704840
  • 239 + 8704601 = 8704840
  • 251 + 8704589 = 8704840

Showing the first eight; more decompositions exist.
