Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122904, here are decompositions:
- 13 + 122891 = 122904
- 17 + 122887 = 122904
- 37 + 122867 = 122904
- 43 + 122861 = 122904
- 71 + 122833 = 122904
- 127 + 122777 = 122904
- 151 + 122753 = 122904
- 163 + 122741 = 122904
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 122,904 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 122904 first appears in π at position 92,115 of the decimal expansion (the 92,115ordinal-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.
