Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485988, here are decompositions:

  • 19 + 2147485969 = 2147485988
  • 61 + 2147485927 = 2147485988
  • 127 + 2147485861 = 2147485988
  • 181 + 2147485807 = 2147485988
  • 229 + 2147485759 = 2147485988
  • 397 + 2147485591 = 2147485988
  • 421 + 2147485567 = 2147485988
  • 541 + 2147485447 = 2147485988

Showing the first eight; more decompositions exist.
