Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147477112, here are decompositions:

  • 5 + 2147477107 = 2147477112
  • 19 + 2147477093 = 2147477112
  • 83 + 2147477029 = 2147477112
  • 149 + 2147476963 = 2147477112
  • 181 + 2147476931 = 2147477112
  • 241 + 2147476871 = 2147477112
  • 271 + 2147476841 = 2147477112
  • 293 + 2147476819 = 2147477112

Showing the first eight; more decompositions exist.
