Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473506, here are decompositions:

  • 19 + 31473487 = 31473506
  • 109 + 31473397 = 31473506
  • 193 + 31473313 = 31473506
  • 223 + 31473283 = 31473506
  • 397 + 31473109 = 31473506
  • 439 + 31473067 = 31473506
  • 523 + 31472983 = 31473506
  • 577 + 31472929 = 31473506

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.63.98.

Address
1.224.63.98
Class
public
IPv4-mapped IPv6
::ffff:1.224.63.98

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

Position in π

The digit sequence 31473506 first appears in π at position 210,106 of the decimal expansion (the 210,106ordinal-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.
