Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467902, here are decompositions:

  • 31 + 2147467871 = 2147467902
  • 89 + 2147467813 = 2147467902
  • 101 + 2147467801 = 2147467902
  • 109 + 2147467793 = 2147467902
  • 191 + 2147467711 = 2147467902
  • 233 + 2147467669 = 2147467902
  • 263 + 2147467639 = 2147467902
  • 271 + 2147467631 = 2147467902

Showing the first eight; more decompositions exist.
