Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467258, here are decompositions:

  • 47 + 2147467211 = 2147467258
  • 89 + 2147467169 = 2147467258
  • 137 + 2147467121 = 2147467258
  • 191 + 2147467067 = 2147467258
  • 311 + 2147466947 = 2147467258
  • 389 + 2147466869 = 2147467258
  • 557 + 2147466701 = 2147467258
  • 617 + 2147466641 = 2147467258

Showing the first eight; more decompositions exist.
