Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613206, here are decompositions:

  • 89 + 31613117 = 31613206
  • 179 + 31613027 = 31613206
  • 293 + 31612913 = 31613206
  • 353 + 31612853 = 31613206
  • 467 + 31612739 = 31613206
  • 479 + 31612727 = 31613206
  • 587 + 31612619 = 31613206
  • 617 + 31612589 = 31613206

Showing the first eight; more decompositions exist.
