Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467798, here are decompositions:

  • 5 + 2147467793 = 2147467798
  • 29 + 2147467769 = 2147467798
  • 101 + 2147467697 = 2147467798
  • 131 + 2147467667 = 2147467798
  • 167 + 2147467631 = 2147467798
  • 239 + 2147467559 = 2147467798
  • 419 + 2147467379 = 2147467798
  • 431 + 2147467367 = 2147467798

Showing the first eight; more decompositions exist.
