Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91998, here are decompositions:

  • 29 + 91969 = 91998
  • 31 + 91967 = 91998
  • 37 + 91961 = 91998
  • 41 + 91957 = 91998
  • 47 + 91951 = 91998
  • 59 + 91939 = 91998
  • 89 + 91909 = 91998
  • 131 + 91867 = 91998

Showing the first eight; more decompositions exist.
