Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140018, here are decompositions:

19 + 139999 = 140018
31 + 139987 = 140018
37 + 139981 = 140018
79 + 139939 = 140018
97 + 139921 = 140018
127 + 139891 = 140018
157 + 139861 = 140018
181 + 139837 = 140018

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 140,018 and was likely granted around 1872.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 140018 first appears in π at position 130,557 of the decimal expansion (the 130,557ordinal-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.
