Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497864, here are decompositions:

  • 107 + 2147497757 = 2147497864
  • 131 + 2147497733 = 2147497864
  • 167 + 2147497697 = 2147497864
  • 173 + 2147497691 = 2147497864
  • 293 + 2147497571 = 2147497864
  • 383 + 2147497481 = 2147497864
  • 461 + 2147497403 = 2147497864
  • 503 + 2147497361 = 2147497864

Showing the first eight; more decompositions exist.
