Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512834, here are decompositions:

  • 7 + 31512827 = 31512834
  • 11 + 31512823 = 31512834
  • 103 + 31512731 = 31512834
  • 131 + 31512703 = 31512834
  • 151 + 31512683 = 31512834
  • 233 + 31512601 = 31512834
  • 277 + 31512557 = 31512834
  • 313 + 31512521 = 31512834

Showing the first eight; more decompositions exist.
