Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497156, here are decompositions:

  • 23 + 2147497133 = 2147497156
  • 113 + 2147497043 = 2147497156
  • 137 + 2147497019 = 2147497156
  • 239 + 2147496917 = 2147497156
  • 293 + 2147496863 = 2147497156
  • 317 + 2147496839 = 2147497156
  • 443 + 2147496713 = 2147497156
  • 449 + 2147496707 = 2147497156

Showing the first eight; more decompositions exist.
