Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143006, here are decompositions:

13 + 142993 = 143006
37 + 142969 = 143006
43 + 142963 = 143006
67 + 142939 = 143006
103 + 142903 = 143006
109 + 142897 = 143006
139 + 142867 = 143006
307 + 142699 = 143006

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 143,006 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 143006 first appears in π at position 190,649 of the decimal expansion (the 190,649ordinal-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.
