Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486796, here are decompositions:

  • 73 + 31486723 = 31486796
  • 139 + 31486657 = 31486796
  • 157 + 31486639 = 31486796
  • 163 + 31486633 = 31486796
  • 193 + 31486603 = 31486796
  • 373 + 31486423 = 31486796
  • 379 + 31486417 = 31486796
  • 409 + 31486387 = 31486796

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.115.76.

Address
1.224.115.76
Class
public
IPv4-mapped IPv6
::ffff:1.224.115.76

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

Position in π

The digit sequence 31486796 first appears in π at position 38,732 of the decimal expansion (the 38,732ordinal-suffix:nd 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.
