Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600998, here are decompositions:

5 + 31600993 = 31600998
29 + 31600969 = 31600998
41 + 31600957 = 31600998
137 + 31600861 = 31600998
139 + 31600859 = 31600998
181 + 31600817 = 31600998
197 + 31600801 = 31600998
199 + 31600799 = 31600998

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.49.102.

Address: 1.226.49.102
Class: public
IPv4-mapped IPv6: ::ffff:1.226.49.102

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

Position in π

The digit sequence 31600998 first appears in π at position 747,188 of the decimal expansion (the 747,188ordinal-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.
