Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971648, here are decompositions:
- 79 + 971569 = 971648
- 127 + 971521 = 971648
- 157 + 971491 = 971648
- 229 + 971419 = 971648
- 277 + 971371 = 971648
- 367 + 971281 = 971648
- 397 + 971251 = 971648
- 499 + 971149 = 971648
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 971,648 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 971648 first appears in π at position 148,805 of the decimal expansion (the 148,805ordinal-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.
