Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40960, here are decompositions:

  • 11 + 40949 = 40960
  • 107 + 40853 = 40960
  • 113 + 40847 = 40960
  • 131 + 40829 = 40960
  • 137 + 40823 = 40960
  • 173 + 40787 = 40960
  • 197 + 40763 = 40960
  • 251 + 40709 = 40960

Showing the first eight; more decompositions exist.
