Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450934, here are decompositions:

  • 37 + 31450897 = 31450934
  • 43 + 31450891 = 31450934
  • 211 + 31450723 = 31450934
  • 313 + 31450621 = 31450934
  • 331 + 31450603 = 31450934
  • 523 + 31450411 = 31450934
  • 547 + 31450387 = 31450934
  • 643 + 31450291 = 31450934

Showing the first eight; more decompositions exist.

As an unsigned 32-bit integer, this is the IPv4 address 1.223.231.54.

Address
1.223.231.54
Class
public
IPv4-mapped IPv6
::ffff:1.223.231.54

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

Position in π

The digit sequence 31450934 first appears in π at position 259,611 of the decimal expansion (the 259,611ordinal-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.
