Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104972, here are decompositions:
- 13 + 104959 = 104972
- 19 + 104953 = 104972
- 61 + 104911 = 104972
- 103 + 104869 = 104972
- 193 + 104779 = 104972
- 199 + 104773 = 104972
- 211 + 104761 = 104972
- 229 + 104743 = 104972
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 104,972 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 104972 first appears in π at position 23,719 of the decimal expansion (the 23,719ordinal-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.
