Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17772, here are decompositions:

  • 11 + 17761 = 17772
  • 23 + 17749 = 17772
  • 43 + 17729 = 17772
  • 59 + 17713 = 17772
  • 89 + 17683 = 17772
  • 103 + 17669 = 17772
  • 113 + 17659 = 17772
  • 149 + 17623 = 17772

Showing the first eight; more decompositions exist.
