Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626548, here are decompositions:

  • 67 + 31626481 = 31626548
  • 127 + 31626421 = 31626548
  • 181 + 31626367 = 31626548
  • 211 + 31626337 = 31626548
  • 439 + 31626109 = 31626548
  • 631 + 31625917 = 31626548
  • 727 + 31625821 = 31626548
  • 769 + 31625779 = 31626548

Showing the first eight; more decompositions exist.

As an unsigned 32-bit integer, this is the IPv4 address 1.226.149.52.

Address
1.226.149.52
Class
public
IPv4-mapped IPv6
::ffff:1.226.149.52

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

Position in π

The digit sequence 31626548 first appears in π at position 28,609 of the decimal expansion (the 28,609ordinal-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.
