Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591840, here are decompositions:

  • 13 + 8591827 = 8591840
  • 31 + 8591809 = 8591840
  • 67 + 8591773 = 8591840
  • 151 + 8591689 = 8591840
  • 157 + 8591683 = 8591840
  • 223 + 8591617 = 8591840
  • 241 + 8591599 = 8591840
  • 277 + 8591563 = 8591840

Showing the first eight; more decompositions exist.
