Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971542, here are decompositions:
- 29 + 971513 = 971542
- 41 + 971501 = 971542
- 59 + 971483 = 971542
- 101 + 971441 = 971542
- 113 + 971429 = 971542
- 233 + 971309 = 971542
- 251 + 971291 = 971542
- 263 + 971279 = 971542
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 971,542 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 971542 first appears in π at position 110,374 of the decimal expansion (the 110,374ordinal-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.
