Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147558212, here are decompositions:

  • 83 + 2147558129 = 2147558212
  • 263 + 2147557949 = 2147558212
  • 509 + 2147557703 = 2147558212
  • 599 + 2147557613 = 2147558212
  • 881 + 2147557331 = 2147558212
  • 911 + 2147557301 = 2147558212
  • 1013 + 2147557199 = 2147558212
  • 1019 + 2147557193 = 2147558212

Showing the first eight; more decompositions exist.
