Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71766, here are decompositions:

  • 5 + 71761 = 71766
  • 47 + 71719 = 71766
  • 53 + 71713 = 71766
  • 59 + 71707 = 71766
  • 67 + 71699 = 71766
  • 73 + 71693 = 71766
  • 103 + 71663 = 71766
  • 173 + 71593 = 71766

Showing the first eight; more decompositions exist.
