Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501128, here are decompositions:

  • 191 + 2147500937 = 2147501128
  • 197 + 2147500931 = 2147501128
  • 239 + 2147500889 = 2147501128
  • 257 + 2147500871 = 2147501128
  • 347 + 2147500781 = 2147501128
  • 431 + 2147500697 = 2147501128
  • 467 + 2147500661 = 2147501128
  • 569 + 2147500559 = 2147501128

Showing the first eight; more decompositions exist.
