Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997904, here are decompositions:
- 7 + 997897 = 997904
- 13 + 997891 = 997904
- 97 + 997807 = 997904
- 163 + 997741 = 997904
- 211 + 997693 = 997904
- 223 + 997681 = 997904
- 241 + 997663 = 997904
- 277 + 997627 = 997904
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 997,904 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 997904 first appears in π at position 143,093 of the decimal expansion (the 143,093ordinal-suffix:rd 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.
