Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528208, here are decompositions:

  • 37 + 31528171 = 31528208
  • 97 + 31528111 = 31528208
  • 139 + 31528069 = 31528208
  • 211 + 31527997 = 31528208
  • 241 + 31527967 = 31528208
  • 277 + 31527931 = 31528208
  • 379 + 31527829 = 31528208
  • 421 + 31527787 = 31528208

Showing the first eight; more decompositions exist.
