Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488032, here are decompositions:

  • 13 + 31488019 = 31488032
  • 19 + 31488013 = 31488032
  • 229 + 31487803 = 31488032
  • 613 + 31487419 = 31488032
  • 769 + 31487263 = 31488032
  • 1033 + 31486999 = 31488032
  • 1051 + 31486981 = 31488032
  • 1321 + 31486711 = 31488032

Showing the first eight; more decompositions exist.
