Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100018, here are decompositions:
- 29 + 99989 = 100018
- 47 + 99971 = 100018
- 89 + 99929 = 100018
- 137 + 99881 = 100018
- 179 + 99839 = 100018
- 251 + 99767 = 100018
- 257 + 99761 = 100018
- 311 + 99707 = 100018
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 100,018 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 100018 first appears in π at position 500,838 of the decimal expansion (the 500,838ordinal-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.
