Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485660, here are decompositions:

  • 11 + 2147485649 = 2147485660
  • 101 + 2147485559 = 2147485660
  • 113 + 2147485547 = 2147485660
  • 137 + 2147485523 = 2147485660
  • 227 + 2147485433 = 2147485660
  • 239 + 2147485421 = 2147485660
  • 317 + 2147485343 = 2147485660
  • 401 + 2147485259 = 2147485660

Showing the first eight; more decompositions exist.
