Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488920, here are decompositions:

  • 7 + 2147488913 = 2147488920
  • 13 + 2147488907 = 2147488920
  • 53 + 2147488867 = 2147488920
  • 61 + 2147488859 = 2147488920
  • 127 + 2147488793 = 2147488920
  • 179 + 2147488741 = 2147488920
  • 193 + 2147488727 = 2147488920
  • 229 + 2147488691 = 2147488920

Showing the first eight; more decompositions exist.
