Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91912, here are decompositions:

  • 3 + 91909 = 91912
  • 71 + 91841 = 91912
  • 89 + 91823 = 91912
  • 101 + 91811 = 91912
  • 131 + 91781 = 91912
  • 179 + 91733 = 91912
  • 239 + 91673 = 91912
  • 281 + 91631 = 91912

Showing the first eight; more decompositions exist.
