Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475224, here are decompositions:

  • 83 + 31475141 = 31475224
  • 113 + 31475111 = 31475224
  • 227 + 31474997 = 31475224
  • 293 + 31474931 = 31475224
  • 461 + 31474763 = 31475224
  • 491 + 31474733 = 31475224
  • 503 + 31474721 = 31475224
  • 647 + 31474577 = 31475224

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.70.24.

Address
1.224.70.24
Class
public
IPv4-mapped IPv6
::ffff:1.224.70.24

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

Position in π

The digit sequence 31475224 first appears in π at position 650,940 of the decimal expansion (the 650,940ordinal-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.
