Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467808, here are decompositions:

  • 7 + 2147467801 = 2147467808
  • 61 + 2147467747 = 2147467808
  • 97 + 2147467711 = 2147467808
  • 139 + 2147467669 = 2147467808
  • 181 + 2147467627 = 2147467808
  • 229 + 2147467579 = 2147467808
  • 337 + 2147467471 = 2147467808
  • 487 + 2147467321 = 2147467808

Showing the first eight; more decompositions exist.
