Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147569980, here are decompositions:

  • 47 + 2147569933 = 2147569980
  • 67 + 2147569913 = 2147569980
  • 139 + 2147569841 = 2147569980
  • 167 + 2147569813 = 2147569980
  • 191 + 2147569789 = 2147569980
  • 197 + 2147569783 = 2147569980
  • 233 + 2147569747 = 2147569980
  • 277 + 2147569703 = 2147569980

Showing the first eight; more decompositions exist.
