Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99072, here are decompositions:

  • 19 + 99053 = 99072
  • 31 + 99041 = 99072
  • 59 + 99013 = 99072
  • 73 + 98999 = 99072
  • 79 + 98993 = 99072
  • 109 + 98963 = 99072
  • 163 + 98909 = 99072
  • 173 + 98899 = 99072

Showing the first eight; more decompositions exist.
