Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485812, here are decompositions:

  • 5 + 2147485807 = 2147485812
  • 53 + 2147485759 = 2147485812
  • 139 + 2147485673 = 2147485812
  • 163 + 2147485649 = 2147485812
  • 239 + 2147485573 = 2147485812
  • 313 + 2147485499 = 2147485812
  • 379 + 2147485433 = 2147485812
  • 389 + 2147485423 = 2147485812

Showing the first eight; more decompositions exist.
