Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467868, here are decompositions:

  • 67 + 2147467801 = 2147467868
  • 109 + 2147467759 = 2147467868
  • 151 + 2147467717 = 2147467868
  • 157 + 2147467711 = 2147467868
  • 199 + 2147467669 = 2147467868
  • 229 + 2147467639 = 2147467868
  • 241 + 2147467627 = 2147467868
  • 397 + 2147467471 = 2147467868

Showing the first eight; more decompositions exist.
