Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547552, here are decompositions:

  • 13 + 31547539 = 31547552
  • 73 + 31547479 = 31547552
  • 103 + 31547449 = 31547552
  • 139 + 31547413 = 31547552
  • 271 + 31547281 = 31547552
  • 349 + 31547203 = 31547552
  • 409 + 31547143 = 31547552
  • 571 + 31546981 = 31547552

Showing the first eight; more decompositions exist.
