Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722012, here are decompositions:

  • 3 + 8722009 = 8722012
  • 11 + 8722001 = 8722012
  • 23 + 8721989 = 8722012
  • 71 + 8721941 = 8722012
  • 83 + 8721929 = 8722012
  • 239 + 8721773 = 8722012
  • 263 + 8721749 = 8722012
  • 311 + 8721701 = 8722012

Showing the first eight; more decompositions exist.
