Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467818, here are decompositions:

  • 7 + 31467811 = 31467818
  • 97 + 31467721 = 31467818
  • 127 + 31467691 = 31467818
  • 229 + 31467589 = 31467818
  • 337 + 31467481 = 31467818
  • 619 + 31467199 = 31467818
  • 661 + 31467157 = 31467818
  • 691 + 31467127 = 31467818

Showing the first eight; more decompositions exist.
