Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147470980, here are decompositions:

  • 41 + 2147470939 = 2147470980
  • 89 + 2147470891 = 2147470980
  • 157 + 2147470823 = 2147470980
  • 191 + 2147470789 = 2147470980
  • 211 + 2147470769 = 2147470980
  • 229 + 2147470751 = 2147470980
  • 257 + 2147470723 = 2147470980
  • 307 + 2147470673 = 2147470980

Showing the first eight; more decompositions exist.
