Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473166, here are decompositions:

  • 283 + 2147472883 = 2147473166
  • 379 + 2147472787 = 2147473166
  • 409 + 2147472757 = 2147473166
  • 823 + 2147472343 = 2147473166
  • 877 + 2147472289 = 2147473166
  • 907 + 2147472259 = 2147473166
  • 967 + 2147472199 = 2147473166
  • 1033 + 2147472133 = 2147473166

Showing the first eight; more decompositions exist.
