Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104872, here are decompositions:
- 3 + 104869 = 104872
- 23 + 104849 = 104872
- 41 + 104831 = 104872
- 71 + 104801 = 104872
- 83 + 104789 = 104872
- 113 + 104759 = 104872
- 149 + 104723 = 104872
- 179 + 104693 = 104872
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 104,872 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 104872 first appears in π at position 44,305 of the decimal expansion (the 44,305ordinal-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.
