Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728372, here are decompositions:

  • 41 + 8728331 = 8728372
  • 83 + 8728289 = 8728372
  • 131 + 8728241 = 8728372
  • 179 + 8728193 = 8728372
  • 293 + 8728079 = 8728372
  • 383 + 8727989 = 8728372
  • 563 + 8727809 = 8728372
  • 593 + 8727779 = 8728372

Showing the first eight; more decompositions exist.
