Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528136, here are decompositions:

  • 43 + 31528093 = 31528136
  • 67 + 31528069 = 31528136
  • 139 + 31527997 = 31528136
  • 223 + 31527913 = 31528136
  • 307 + 31527829 = 31528136
  • 349 + 31527787 = 31528136
  • 433 + 31527703 = 31528136
  • 439 + 31527697 = 31528136

Showing the first eight; more decompositions exist.
