Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7972, here are decompositions:

  • 23 + 7949 = 7972
  • 53 + 7919 = 7972
  • 71 + 7901 = 7972
  • 89 + 7883 = 7972
  • 131 + 7841 = 7972
  • 149 + 7823 = 7972
  • 179 + 7793 = 7972
  • 269 + 7703 = 7972

Showing the first eight; more decompositions exist.
