Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467892, here are decompositions:

  • 79 + 2147467813 = 2147467892
  • 181 + 2147467711 = 2147467892
  • 223 + 2147467669 = 2147467892
  • 313 + 2147467579 = 2147467892
  • 421 + 2147467471 = 2147467892
  • 499 + 2147467393 = 2147467892
  • 571 + 2147467321 = 2147467892
  • 631 + 2147467261 = 2147467892

Showing the first eight; more decompositions exist.
