Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468146, here are decompositions:

  • 179 + 2147467967 = 2147468146
  • 227 + 2147467919 = 2147468146
  • 353 + 2147467793 = 2147468146
  • 449 + 2147467697 = 2147468146
  • 479 + 2147467667 = 2147468146
  • 563 + 2147467583 = 2147468146
  • 587 + 2147467559 = 2147468146
  • 653 + 2147467493 = 2147468146

Showing the first eight; more decompositions exist.
