Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 964440, here are decompositions:
- 7 + 964433 = 964440
- 17 + 964423 = 964440
- 23 + 964417 = 964440
- 67 + 964373 = 964440
- 83 + 964357 = 964440
- 89 + 964351 = 964440
- 101 + 964339 = 964440
- 107 + 964333 = 964440
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 964,440 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 964440 first appears in π at position 102,906 of the decimal expansion (the 102,906ordinal-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.
