Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497320, here are decompositions:

  • 83 + 2147497237 = 2147497320
  • 179 + 2147497141 = 2147497320
  • 239 + 2147497081 = 2147497320
  • 277 + 2147497043 = 2147497320
  • 281 + 2147497039 = 2147497320
  • 349 + 2147496971 = 2147497320
  • 359 + 2147496961 = 2147497320
  • 379 + 2147496941 = 2147497320

Showing the first eight; more decompositions exist.
