Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87072, here are decompositions:

  • 23 + 87049 = 87072
  • 31 + 87041 = 87072
  • 59 + 87013 = 87072
  • 61 + 87011 = 87072
  • 79 + 86993 = 87072
  • 103 + 86969 = 87072
  • 113 + 86959 = 87072
  • 149 + 86923 = 87072

Showing the first eight; more decompositions exist.
