Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445934, here are decompositions:

  • 5 + 31445929 = 31445934
  • 17 + 31445917 = 31445934
  • 43 + 31445891 = 31445934
  • 71 + 31445863 = 31445934
  • 73 + 31445861 = 31445934
  • 83 + 31445851 = 31445934
  • 101 + 31445833 = 31445934
  • 211 + 31445723 = 31445934

Showing the first eight; more decompositions exist.
