Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100240, here are decompositions:
- 3 + 100237 = 100240
- 47 + 100193 = 100240
- 71 + 100169 = 100240
- 89 + 100151 = 100240
- 131 + 100109 = 100240
- 137 + 100103 = 100240
- 191 + 100049 = 100240
- 197 + 100043 = 100240
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 100,240 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 100240 first appears in π at position 194,015 of the decimal expansion (the 194,015ordinal-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.
