Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613098, here are decompositions:

71 + 31613027 = 31613098
107 + 31612991 = 31613098
137 + 31612961 = 31613098
359 + 31612739 = 31613098
431 + 31612667 = 31613098
479 + 31612619 = 31613098
509 + 31612589 = 31613098
617 + 31612481 = 31613098

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.96.170.

Address: 1.226.96.170
Class: public
IPv4-mapped IPv6: ::ffff:1.226.96.170

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

Position in π

The digit sequence 31613098 first appears in π at position 212,998 of the decimal expansion (the 212,998ordinal-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.
