Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470998, here are decompositions:

  • 7 + 31470991 = 31470998
  • 109 + 31470889 = 31470998
  • 151 + 31470847 = 31470998
  • 199 + 31470799 = 31470998
  • 211 + 31470787 = 31470998
  • 277 + 31470721 = 31470998
  • 337 + 31470661 = 31470998
  • 379 + 31470619 = 31470998

Showing the first eight; more decompositions exist.
