Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556000, here are decompositions:

  • 3 + 33555997 = 33556000
  • 11 + 33555989 = 33556000
  • 29 + 33555971 = 33556000
  • 41 + 33555959 = 33556000
  • 53 + 33555947 = 33556000
  • 263 + 33555737 = 33556000
  • 353 + 33555647 = 33556000
  • 383 + 33555617 = 33556000

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.6.32.
