Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485816, here are decompositions:

  • 167 + 2147485649 = 2147485816
  • 257 + 2147485559 = 2147485816
  • 269 + 2147485547 = 2147485816
  • 293 + 2147485523 = 2147485816
  • 317 + 2147485499 = 2147485816
  • 383 + 2147485433 = 2147485816
  • 479 + 2147485337 = 2147485816
  • 557 + 2147485259 = 2147485816

Showing the first eight; more decompositions exist.
