Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599122, here are decompositions:

  • 19 + 31599103 = 31599122
  • 199 + 31598923 = 31599122
  • 211 + 31598911 = 31599122
  • 283 + 31598839 = 31599122
  • 421 + 31598701 = 31599122
  • 439 + 31598683 = 31599122
  • 601 + 31598521 = 31599122
  • 673 + 31598449 = 31599122

Showing the first eight; more decompositions exist.
