Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100372, here are decompositions:
- 11 + 100361 = 100372
- 29 + 100343 = 100372
- 59 + 100313 = 100372
- 101 + 100271 = 100372
- 179 + 100193 = 100372
- 263 + 100109 = 100372
- 269 + 100103 = 100372
- 353 + 100019 = 100372
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 100,372 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 100372 first appears in π at position 236,632 of the decimal expansion (the 236,632ordinal-suffix:nd 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.
