Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467998, here are decompositions:

  • 31 + 2147467967 = 2147467998
  • 79 + 2147467919 = 2147467998
  • 127 + 2147467871 = 2147467998
  • 197 + 2147467801 = 2147467998
  • 229 + 2147467769 = 2147467998
  • 239 + 2147467759 = 2147467998
  • 251 + 2147467747 = 2147467998
  • 281 + 2147467717 = 2147467998

Showing the first eight; more decompositions exist.
