Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472762, here are decompositions:

  • 5 + 2147472757 = 2147472762
  • 11 + 2147472751 = 2147472762
  • 73 + 2147472689 = 2147472762
  • 79 + 2147472683 = 2147472762
  • 103 + 2147472659 = 2147472762
  • 151 + 2147472611 = 2147472762
  • 263 + 2147472499 = 2147472762
  • 271 + 2147472491 = 2147472762

Showing the first eight; more decompositions exist.
