Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100724, here are decompositions:
- 31 + 100693 = 100724
- 103 + 100621 = 100724
- 223 + 100501 = 100724
- 241 + 100483 = 100724
- 277 + 100447 = 100724
- 307 + 100417 = 100724
- 313 + 100411 = 100724
- 331 + 100393 = 100724
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 100,724 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 100724 first appears in π at position 465,368 of the decimal expansion (the 465,368ordinal-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.
