Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467572, here are decompositions:

  • 13 + 2147467559 = 2147467572
  • 79 + 2147467493 = 2147467572
  • 101 + 2147467471 = 2147467572
  • 109 + 2147467463 = 2147467572
  • 179 + 2147467393 = 2147467572
  • 193 + 2147467379 = 2147467572
  • 233 + 2147467339 = 2147467572
  • 241 + 2147467331 = 2147467572

Showing the first eight; more decompositions exist.
