Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603316, here are decompositions:

  • 7 + 31603309 = 31603316
  • 67 + 31603249 = 31603316
  • 193 + 31603123 = 31603316
  • 307 + 31603009 = 31603316
  • 439 + 31602877 = 31603316
  • 457 + 31602859 = 31603316
  • 463 + 31602853 = 31603316
  • 523 + 31602793 = 31603316

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.58.116.

Address
1.226.58.116
Class
public
IPv4-mapped IPv6
::ffff:1.226.58.116

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

Position in π

The digit sequence 31603316 first appears in π at position 70,108 of the decimal expansion (the 70,108ordinal-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.
