Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604884, here are decompositions:

  • 137 + 31604747 = 31604884
  • 197 + 31604687 = 31604884
  • 257 + 31604627 = 31604884
  • 281 + 31604603 = 31604884
  • 383 + 31604501 = 31604884
  • 431 + 31604453 = 31604884
  • 587 + 31604297 = 31604884
  • 827 + 31604057 = 31604884

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.64.148.

Address
1.226.64.148
Class
public
IPv4-mapped IPv6
::ffff:1.226.64.148

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

Position in π

The digit sequence 31604884 first appears in π at position 556,508 of the decimal expansion (the 556,508ordinal-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.
