Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473172, here are decompositions:

  • 421 + 2147472751 = 2147473172
  • 571 + 2147472601 = 2147473172
  • 673 + 2147472499 = 2147473172
  • 751 + 2147472421 = 2147473172
  • 829 + 2147472343 = 2147473172
  • 883 + 2147472289 = 2147473172
  • 1039 + 2147472133 = 2147473172
  • 1063 + 2147472109 = 2147473172

Showing the first eight; more decompositions exist.
