Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122108, here are decompositions:
- 67 + 122041 = 122108
- 79 + 122029 = 122108
- 97 + 122011 = 122108
- 157 + 121951 = 122108
- 199 + 121909 = 122108
- 241 + 121867 = 122108
- 397 + 121711 = 122108
- 421 + 121687 = 122108
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 122,108 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 122108 first appears in π at position 716,113 of the decimal expansion (the 716,113ordinal-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.
