Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124904, here are decompositions:
- 7 + 124897 = 124904
- 127 + 124777 = 124904
- 151 + 124753 = 124904
- 211 + 124693 = 124904
- 271 + 124633 = 124904
- 337 + 124567 = 124904
- 433 + 124471 = 124904
- 457 + 124447 = 124904
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 124,904 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 124904 first appears in π at position 696,016 of the decimal expansion (the 696,016ordinal-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.
