Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497476, here are decompositions:

  • 17 + 2147497459 = 2147497476
  • 29 + 2147497447 = 2147497476
  • 73 + 2147497403 = 2147497476
  • 83 + 2147497393 = 2147497476
  • 127 + 2147497349 = 2147497476
  • 233 + 2147497243 = 2147497476
  • 239 + 2147497237 = 2147497476
  • 433 + 2147497043 = 2147497476

Showing the first eight; more decompositions exist.
