Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971842, here are decompositions:
- 59 + 971783 = 971842
- 83 + 971759 = 971842
- 89 + 971753 = 971842
- 149 + 971693 = 971842
- 191 + 971651 = 971842
- 251 + 971591 = 971842
- 281 + 971561 = 971842
- 293 + 971549 = 971842
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 971,842 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 971842 first appears in π at position 30,736 of the decimal expansion (the 30,736ordinal-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.
