Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591838, here are decompositions:

  • 7 + 8591831 = 8591838
  • 11 + 8591827 = 8591838
  • 29 + 8591809 = 8591838
  • 67 + 8591771 = 8591838
  • 127 + 8591711 = 8591838
  • 149 + 8591689 = 8591838
  • 239 + 8591599 = 8591838
  • 251 + 8591587 = 8591838

Showing the first eight; more decompositions exist.
