Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472746, here are decompositions:

  • 277 + 2147472469 = 2147472746
  • 373 + 2147472373 = 2147472746
  • 457 + 2147472289 = 2147472746
  • 487 + 2147472259 = 2147472746
  • 547 + 2147472199 = 2147472746
  • 613 + 2147472133 = 2147472746
  • 709 + 2147472037 = 2147472746
  • 883 + 2147471863 = 2147472746

Showing the first eight; more decompositions exist.
