Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497472, here are decompositions:

  • 13 + 2147497459 = 2147497472
  • 61 + 2147497411 = 2147497472
  • 79 + 2147497393 = 2147497472
  • 151 + 2147497321 = 2147497472
  • 229 + 2147497243 = 2147497472
  • 271 + 2147497201 = 2147497472
  • 331 + 2147497141 = 2147497472
  • 433 + 2147497039 = 2147497472

Showing the first eight; more decompositions exist.
