Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523024, here are decompositions:

  • 3 + 31523021 = 31523024
  • 37 + 31522987 = 31523024
  • 73 + 31522951 = 31523024
  • 151 + 31522873 = 31523024
  • 277 + 31522747 = 31523024
  • 307 + 31522717 = 31523024
  • 331 + 31522693 = 31523024
  • 367 + 31522657 = 31523024

Showing the first eight; more decompositions exist.
