Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471060, here are decompositions:

  • 17 + 31471043 = 31471060
  • 29 + 31471031 = 31471060
  • 53 + 31471007 = 31471060
  • 59 + 31471001 = 31471060
  • 83 + 31470977 = 31471060
  • 107 + 31470953 = 31471060
  • 149 + 31470911 = 31471060
  • 191 + 31470869 = 31471060

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.53.212.

Address
1.224.53.212
Class
public
IPv4-mapped IPv6
::ffff:1.224.53.212

Public, routable address (assignable to a host on the internet).

Position in π

The digit sequence 31471060 first appears in π at position 537,818 of the decimal expansion (the 537,818ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
