Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467970, here are decompositions:

  • 3 + 2147467967 = 2147467970
  • 7 + 2147467963 = 2147467970
  • 157 + 2147467813 = 2147467970
  • 211 + 2147467759 = 2147467970
  • 223 + 2147467747 = 2147467970
  • 331 + 2147467639 = 2147467970
  • 499 + 2147467471 = 2147467970
  • 577 + 2147467393 = 2147467970

Showing the first eight; more decompositions exist.
