Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77072, here are decompositions:

  • 3 + 77069 = 77072
  • 31 + 77041 = 77072
  • 43 + 77029 = 77072
  • 109 + 76963 = 77072
  • 199 + 76873 = 77072
  • 241 + 76831 = 77072
  • 271 + 76801 = 77072
  • 421 + 76651 = 77072

Showing the first eight; more decompositions exist.
