Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87874, here are decompositions:

  • 5 + 87869 = 87874
  • 41 + 87833 = 87874
  • 71 + 87803 = 87874
  • 107 + 87767 = 87874
  • 131 + 87743 = 87874
  • 173 + 87701 = 87874
  • 191 + 87683 = 87874
  • 233 + 87641 = 87874

Showing the first eight; more decompositions exist.
