Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104072, here are decompositions:
- 13 + 104059 = 104072
- 19 + 104053 = 104072
- 79 + 103993 = 104072
- 103 + 103969 = 104072
- 109 + 103963 = 104072
- 229 + 103843 = 104072
- 271 + 103801 = 104072
- 349 + 103723 = 104072
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 104,072 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 104072 first appears in π at position 382,899 of the decimal expansion (the 382,899ordinal-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.
