Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466820, here are decompositions:

  • 137 + 2147466683 = 2147466820
  • 179 + 2147466641 = 2147466820
  • 281 + 2147466539 = 2147466820
  • 461 + 2147466359 = 2147466820
  • 491 + 2147466329 = 2147466820
  • 557 + 2147466263 = 2147466820
  • 563 + 2147466257 = 2147466820
  • 593 + 2147466227 = 2147466820

Showing the first eight; more decompositions exist.
