Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71864, here are decompositions:

  • 3 + 71861 = 71864
  • 43 + 71821 = 71864
  • 103 + 71761 = 71864
  • 151 + 71713 = 71864
  • 157 + 71707 = 71864
  • 193 + 71671 = 71864
  • 271 + 71593 = 71864
  • 313 + 71551 = 71864

Showing the first eight; more decompositions exist.
