Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468368, here are decompositions:

  • 137 + 2147468231 = 2147468368
  • 179 + 2147468189 = 2147468368
  • 401 + 2147467967 = 2147468368
  • 449 + 2147467919 = 2147468368
  • 599 + 2147467769 = 2147468368
  • 701 + 2147467667 = 2147468368
  • 809 + 2147467559 = 2147468368
  • 1301 + 2147467067 = 2147468368

Showing the first eight; more decompositions exist.
