Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121108, here are decompositions:
- 41 + 121067 = 121108
- 47 + 121061 = 121108
- 89 + 121019 = 121108
- 101 + 121007 = 121108
- 107 + 121001 = 121108
- 131 + 120977 = 121108
- 167 + 120941 = 121108
- 179 + 120929 = 121108
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 121,108 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 121108 first appears in π at position 783,560 of the decimal expansion (the 783,560ordinal-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.
