Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148904, here are decompositions:
- 13 + 148891 = 148904
- 31 + 148873 = 148904
- 37 + 148867 = 148904
- 43 + 148861 = 148904
- 157 + 148747 = 148904
- 181 + 148723 = 148904
- 193 + 148711 = 148904
- 211 + 148693 = 148904
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 148,904 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 148904 first appears in π at position 619,625 of the decimal expansion (the 619,625ordinal-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.
