Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546874, here are decompositions:

  • 13 + 31546861 = 31546874
  • 31 + 31546843 = 31546874
  • 43 + 31546831 = 31546874
  • 61 + 31546813 = 31546874
  • 67 + 31546807 = 31546874
  • 157 + 31546717 = 31546874
  • 211 + 31546663 = 31546874
  • 241 + 31546633 = 31546874

Showing the first eight; more decompositions exist.
