Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649884, here are decompositions:

  • 3 + 8649881 = 8649884
  • 13 + 8649871 = 8649884
  • 31 + 8649853 = 8649884
  • 37 + 8649847 = 8649884
  • 127 + 8649757 = 8649884
  • 163 + 8649721 = 8649884
  • 181 + 8649703 = 8649884
  • 193 + 8649691 = 8649884

Showing the first eight; more decompositions exist.
