Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472538, here are decompositions:

  • 47 + 2147472491 = 2147472538
  • 89 + 2147472449 = 2147472538
  • 227 + 2147472311 = 2147472538
  • 317 + 2147472221 = 2147472538
  • 401 + 2147472137 = 2147472538
  • 467 + 2147472071 = 2147472538
  • 587 + 2147471951 = 2147472538
  • 599 + 2147471939 = 2147472538

Showing the first eight; more decompositions exist.
