Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33622840, here are decompositions:

  • 59 + 33622781 = 33622840
  • 71 + 33622769 = 33622840
  • 107 + 33622733 = 33622840
  • 113 + 33622727 = 33622840
  • 137 + 33622703 = 33622840
  • 149 + 33622691 = 33622840
  • 197 + 33622643 = 33622840
  • 227 + 33622613 = 33622840

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.1.11.56.
