Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591616, here are decompositions:

  • 13 + 8591603 = 8591616
  • 17 + 8591599 = 8591616
  • 23 + 8591593 = 8591616
  • 29 + 8591587 = 8591616
  • 43 + 8591573 = 8591616
  • 53 + 8591563 = 8591616
  • 67 + 8591549 = 8591616
  • 73 + 8591543 = 8591616

Showing the first eight; more decompositions exist.
