Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618742, here are decompositions:

  • 5 + 8618737 = 8618742
  • 43 + 8618699 = 8618742
  • 53 + 8618689 = 8618742
  • 59 + 8618683 = 8618742
  • 61 + 8618681 = 8618742
  • 103 + 8618639 = 8618742
  • 149 + 8618593 = 8618742
  • 151 + 8618591 = 8618742

Showing the first eight; more decompositions exist.
