Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961644, here are decompositions:
- 7 + 961637 = 961644
- 11 + 961633 = 961644
- 17 + 961627 = 961644
- 31 + 961613 = 961644
- 43 + 961601 = 961644
- 97 + 961547 = 961644
- 113 + 961531 = 961644
- 137 + 961507 = 961644
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 961,644 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 961644 first appears in π at position 57,434 of the decimal expansion (the 57,434ordinal-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.
