Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467800, here are decompositions:

  • 37 + 31467763 = 31467800
  • 73 + 31467727 = 31467800
  • 79 + 31467721 = 31467800
  • 109 + 31467691 = 31467800
  • 211 + 31467589 = 31467800
  • 229 + 31467571 = 31467800
  • 241 + 31467559 = 31467800
  • 367 + 31467433 = 31467800

Showing the first eight; more decompositions exist.
