Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104638, here are decompositions:
- 41 + 104597 = 104638
- 59 + 104579 = 104638
- 89 + 104549 = 104638
- 101 + 104537 = 104638
- 167 + 104471 = 104638
- 179 + 104459 = 104638
- 239 + 104399 = 104638
- 257 + 104381 = 104638
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 104,638 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 104638 first appears in π at position 729,854 of the decimal expansion (the 729,854ordinal-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.
