Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961000, here are decompositions:
- 11 + 960989 = 961000
- 17 + 960983 = 961000
- 23 + 960977 = 961000
- 59 + 960941 = 961000
- 137 + 960863 = 961000
- 167 + 960833 = 961000
- 191 + 960809 = 961000
- 197 + 960803 = 961000
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 961,000 and was likely granted around 1910.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 961000 first appears in π at position 741,177 of the decimal expansion (the 741,177ordinal-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.
