Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131044, here are decompositions:

3 + 131041 = 131044
71 + 130973 = 131044
227 + 130817 = 131044
233 + 130811 = 131044
257 + 130787 = 131044
401 + 130643 = 131044
491 + 130553 = 131044
521 + 130523 = 131044

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 131,044 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 131044 first appears in π at position 630,806 of the decimal expansion (the 630,806ordinal-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.
