Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71100, here are decompositions:

  • 11 + 71089 = 71100
  • 19 + 71081 = 71100
  • 31 + 71069 = 71100
  • 41 + 71059 = 71100
  • 61 + 71039 = 71100
  • 89 + 71011 = 71100
  • 101 + 70999 = 71100
  • 103 + 70997 = 71100

Showing the first eight; more decompositions exist.
