Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474522, here are decompositions:

  • 3 + 31474519 = 31474522
  • 41 + 31474481 = 31474522
  • 89 + 31474433 = 31474522
  • 179 + 31474343 = 31474522
  • 269 + 31474253 = 31474522
  • 449 + 31474073 = 31474522
  • 461 + 31474061 = 31474522
  • 479 + 31474043 = 31474522

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.67.90.

Address
1.224.67.90
Class
public
IPv4-mapped IPv6
::ffff:1.224.67.90

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

Position in π

The digit sequence 31474522 first appears in π at position 735,706 of the decimal expansion (the 735,706ordinal-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.
