Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467566, here are decompositions:

  • 7 + 2147467559 = 2147467566
  • 73 + 2147467493 = 2147467566
  • 103 + 2147467463 = 2147467566
  • 163 + 2147467403 = 2147467566
  • 173 + 2147467393 = 2147467566
  • 199 + 2147467367 = 2147467566
  • 227 + 2147467339 = 2147467566
  • 239 + 2147467327 = 2147467566

Showing the first eight; more decompositions exist.
