Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467218, here are decompositions:

  • 7 + 2147467211 = 2147467218
  • 97 + 2147467121 = 2147467218
  • 151 + 2147467067 = 2147467218
  • 227 + 2147466991 = 2147467218
  • 271 + 2147466947 = 2147467218
  • 349 + 2147466869 = 2147467218
  • 431 + 2147466787 = 2147467218
  • 577 + 2147466641 = 2147467218

Showing the first eight; more decompositions exist.
