Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108198, here are decompositions:
- 5 + 108193 = 108198
- 7 + 108191 = 108198
- 11 + 108187 = 108198
- 19 + 108179 = 108198
- 37 + 108161 = 108198
- 59 + 108139 = 108198
- 67 + 108131 = 108198
- 71 + 108127 = 108198
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 108,198 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 108198 first appears in π at position 663,963 of the decimal expansion (the 663,963ordinal-suffix:rd 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.
