Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485686, here are decompositions:

  • 13 + 2147485673 = 2147485686
  • 37 + 2147485649 = 2147485686
  • 113 + 2147485573 = 2147485686
  • 127 + 2147485559 = 2147485686
  • 139 + 2147485547 = 2147485686
  • 163 + 2147485523 = 2147485686
  • 239 + 2147485447 = 2147485686
  • 263 + 2147485423 = 2147485686

Showing the first eight; more decompositions exist.
