Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550952, here are decompositions:

  • 5 + 31550947 = 31550952
  • 29 + 31550923 = 31550952
  • 31 + 31550921 = 31550952
  • 73 + 31550879 = 31550952
  • 101 + 31550851 = 31550952
  • 149 + 31550803 = 31550952
  • 151 + 31550801 = 31550952
  • 229 + 31550723 = 31550952

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.109.232.

Address
1.225.109.232
Class

IPv4-mapped IPv6
::ffff:1.225.109.232

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

Position in π

The digit sequence 31550952 first appears in π at position 131,314 of the decimal expansion (the 131,314ordinal-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.
