Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147456266, here are decompositions:

  • 149 + 2147456117 = 2147456266
  • 359 + 2147455907 = 2147456266
  • 563 + 2147455703 = 2147456266
  • 653 + 2147455613 = 2147456266
  • 719 + 2147455547 = 2147456266
  • 743 + 2147455523 = 2147456266
  • 863 + 2147455403 = 2147456266
  • 953 + 2147455313 = 2147456266

Showing the first eight; more decompositions exist.
