Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528430, here are decompositions:

  • 67 + 31528363 = 31528430
  • 103 + 31528327 = 31528430
  • 139 + 31528291 = 31528430
  • 151 + 31528279 = 31528430
  • 163 + 31528267 = 31528430
  • 223 + 31528207 = 31528430
  • 337 + 31528093 = 31528430
  • 433 + 31527997 = 31528430

Showing the first eight; more decompositions exist.
