Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997664, here are decompositions:
- 13 + 997651 = 997664
- 37 + 997627 = 997664
- 67 + 997597 = 997664
- 211 + 997453 = 997664
- 307 + 997357 = 997664
- 331 + 997333 = 997664
- 337 + 997327 = 997664
- 397 + 997267 = 997664
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 997,664 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 997664 first appears in π at position 562,520 of the decimal expansion (the 562,520ordinal-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.
