Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613328, here are decompositions:

  • 37 + 31613291 = 31613328
  • 79 + 31613249 = 31613328
  • 101 + 31613227 = 31613328
  • 137 + 31613191 = 31613328
  • 157 + 31613171 = 31613328
  • 191 + 31613137 = 31613328
  • 211 + 31613117 = 31613328
  • 337 + 31612991 = 31613328

Showing the first eight; more decompositions exist.
