Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 996640, here are decompositions:
- 3 + 996637 = 996640
- 11 + 996629 = 996640
- 23 + 996617 = 996640
- 41 + 996599 = 996640
- 89 + 996551 = 996640
- 101 + 996539 = 996640
- 179 + 996461 = 996640
- 233 + 996407 = 996640
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 996,640 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 996640 first appears in π at position 418,509 of the decimal expansion (the 418,509ordinal-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.
