Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64170, here are decompositions:

  • 13 + 64157 = 64170
  • 17 + 64153 = 64170
  • 19 + 64151 = 64170
  • 47 + 64123 = 64170
  • 61 + 64109 = 64170
  • 79 + 64091 = 64170
  • 89 + 64081 = 64170
  • 103 + 64067 = 64170

Showing the first eight; more decompositions exist.
