Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127104, here are decompositions:
- 23 + 127081 = 127104
- 53 + 127051 = 127104
- 67 + 127037 = 127104
- 71 + 127033 = 127104
- 73 + 127031 = 127104
- 137 + 126967 = 127104
- 181 + 126923 = 127104
- 191 + 126913 = 127104
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 127,104 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 127104 first appears in π at position 382,201 of the decimal expansion (the 382,201ordinal-suffix:st 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.
