Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31772, here are decompositions:

  • 3 + 31769 = 31772
  • 31 + 31741 = 31772
  • 43 + 31729 = 31772
  • 73 + 31699 = 31772
  • 109 + 31663 = 31772
  • 199 + 31573 = 31772
  • 229 + 31543 = 31772
  • 241 + 31531 = 31772

Showing the first eight; more decompositions exist.
