Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467898, here are decompositions:

  • 97 + 2147467801 = 2147467898
  • 139 + 2147467759 = 2147467898
  • 151 + 2147467747 = 2147467898
  • 181 + 2147467717 = 2147467898
  • 229 + 2147467669 = 2147467898
  • 271 + 2147467627 = 2147467898
  • 571 + 2147467327 = 2147467898
  • 577 + 2147467321 = 2147467898

Showing the first eight; more decompositions exist.
