Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961400, here are decompositions:
- 3 + 961397 = 961400
- 7 + 961393 = 961400
- 61 + 961339 = 961400
- 127 + 961273 = 961400
- 157 + 961243 = 961400
- 199 + 961201 = 961400
- 211 + 961189 = 961400
- 241 + 961159 = 961400
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 961,400 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 961400 first appears in π at position 389,195 of the decimal expansion (the 389,195ordinal-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.
