Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147552782, here are decompositions:

  • 5 + 2147552777 = 2147552782
  • 29 + 2147552753 = 2147552782
  • 59 + 2147552723 = 2147552782
  • 239 + 2147552543 = 2147552782
  • 251 + 2147552531 = 2147552782
  • 269 + 2147552513 = 2147552782
  • 359 + 2147552423 = 2147552782
  • 443 + 2147552339 = 2147552782

Showing the first eight; more decompositions exist.
