Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467774, here are decompositions:

  • 5 + 2147467769 = 2147467774
  • 41 + 2147467733 = 2147467774
  • 107 + 2147467667 = 2147467774
  • 191 + 2147467583 = 2147467774
  • 281 + 2147467493 = 2147467774
  • 311 + 2147467463 = 2147467774
  • 443 + 2147467331 = 2147467774
  • 563 + 2147467211 = 2147467774

Showing the first eight; more decompositions exist.
