Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87958, here are decompositions:

  • 41 + 87917 = 87958
  • 47 + 87911 = 87958
  • 71 + 87887 = 87958
  • 89 + 87869 = 87958
  • 191 + 87767 = 87958
  • 239 + 87719 = 87958
  • 257 + 87701 = 87958
  • 317 + 87641 = 87958

Showing the first eight; more decompositions exist.
