Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479322, here are decompositions:

  • 23 + 31479299 = 31479322
  • 53 + 31479269 = 31479322
  • 71 + 31479251 = 31479322
  • 191 + 31479131 = 31479322
  • 239 + 31479083 = 31479322
  • 353 + 31478969 = 31479322
  • 389 + 31478933 = 31479322
  • 491 + 31478831 = 31479322

Showing the first eight; more decompositions exist.
