Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547612, here are decompositions:

  • 3 + 31547609 = 31547612
  • 73 + 31547539 = 31547612
  • 163 + 31547449 = 31547612
  • 199 + 31547413 = 31547612
  • 331 + 31547281 = 31547612
  • 409 + 31547203 = 31547612
  • 631 + 31546981 = 31547612
  • 643 + 31546969 = 31547612

Showing the first eight; more decompositions exist.
