Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462242, here are decompositions:

101 + 31462141 = 31462242
109 + 31462133 = 31462242
139 + 31462103 = 31462242
173 + 31462069 = 31462242
239 + 31462003 = 31462242
263 + 31461979 = 31462242
281 + 31461961 = 31462242
293 + 31461949 = 31462242

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.19.98.

Address: 1.224.19.98
Class: public
IPv4-mapped IPv6: ::ffff:1.224.19.98

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

Position in π

The digit sequence 31462242 first appears in π at position 486,029 of the decimal expansion (the 486,029ordinal-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.
