Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100518, here are decompositions:
- 7 + 100511 = 100518
- 17 + 100501 = 100518
- 59 + 100459 = 100518
- 71 + 100447 = 100518
- 101 + 100417 = 100518
- 107 + 100411 = 100518
- 127 + 100391 = 100518
- 139 + 100379 = 100518
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 100,518 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 100518 first appears in π at position 242,668 of the decimal expansion (the 242,668ordinal-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.
