Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71760, here are decompositions:

  • 19 + 71741 = 71760
  • 41 + 71719 = 71760
  • 47 + 71713 = 71760
  • 53 + 71707 = 71760
  • 61 + 71699 = 71760
  • 67 + 71693 = 71760
  • 89 + 71671 = 71760
  • 97 + 71663 = 71760

Showing the first eight; more decompositions exist.
