Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971242, here are decompositions:
- 5 + 971237 = 971242
- 71 + 971171 = 971242
- 89 + 971153 = 971242
- 101 + 971141 = 971242
- 131 + 971111 = 971242
- 149 + 971093 = 971242
- 179 + 971063 = 971242
- 191 + 971051 = 971242
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 971,242 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 971242 first appears in π at position 452,969 of the decimal expansion (the 452,969ordinal-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.
