Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468242, here are decompositions:

  • 11 + 2147468231 = 2147468242
  • 53 + 2147468189 = 2147468242
  • 173 + 2147468069 = 2147468242
  • 239 + 2147468003 = 2147468242
  • 449 + 2147467793 = 2147468242
  • 509 + 2147467733 = 2147468242
  • 659 + 2147467583 = 2147468242
  • 683 + 2147467559 = 2147468242

Showing the first eight; more decompositions exist.
