Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488472, here are decompositions:

  • 43 + 2147488429 = 2147488472
  • 61 + 2147488411 = 2147488472
  • 139 + 2147488333 = 2147488472
  • 193 + 2147488279 = 2147488472
  • 223 + 2147488249 = 2147488472
  • 463 + 2147488009 = 2147488472
  • 541 + 2147487931 = 2147488472
  • 601 + 2147487871 = 2147488472

Showing the first eight; more decompositions exist.
