Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723684, here are decompositions:

  • 7 + 8723677 = 8723684
  • 31 + 8723653 = 8723684
  • 163 + 8723521 = 8723684
  • 331 + 8723353 = 8723684
  • 337 + 8723347 = 8723684
  • 367 + 8723317 = 8723684
  • 373 + 8723311 = 8723684
  • 547 + 8723137 = 8723684

Showing the first eight; more decompositions exist.
