Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971784, here are decompositions:
- 17 + 971767 = 971784
- 31 + 971753 = 971784
- 61 + 971723 = 971784
- 71 + 971713 = 971784
- 101 + 971683 = 971784
- 131 + 971653 = 971784
- 193 + 971591 = 971784
- 223 + 971561 = 971784
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 971,784 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 971784 first appears in π at position 337,448 of the decimal expansion (the 337,448ordinal-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.
