Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522916, here are decompositions:

  • 43 + 31522873 = 31522916
  • 199 + 31522717 = 31522916
  • 223 + 31522693 = 31522916
  • 283 + 31522633 = 31522916
  • 367 + 31522549 = 31522916
  • 457 + 31522459 = 31522916
  • 577 + 31522339 = 31522916
  • 619 + 31522297 = 31522916

Showing the first eight; more decompositions exist.
