Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468386, here are decompositions:

  • 137 + 2147468249 = 2147468386
  • 197 + 2147468189 = 2147468386
  • 317 + 2147468069 = 2147468386
  • 383 + 2147468003 = 2147468386
  • 419 + 2147467967 = 2147468386
  • 467 + 2147467919 = 2147468386
  • 593 + 2147467793 = 2147468386
  • 617 + 2147467769 = 2147468386

Showing the first eight; more decompositions exist.
