Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13100, here are decompositions:

  • 7 + 13093 = 13100
  • 37 + 13063 = 13100
  • 67 + 13033 = 13100
  • 97 + 13003 = 13100
  • 127 + 12973 = 13100
  • 181 + 12919 = 13100
  • 193 + 12907 = 13100
  • 211 + 12889 = 13100

Showing the first eight; more decompositions exist.
