Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108220, here are decompositions:
- 3 + 108217 = 108220
- 17 + 108203 = 108220
- 29 + 108191 = 108220
- 41 + 108179 = 108220
- 59 + 108161 = 108220
- 89 + 108131 = 108220
- 113 + 108107 = 108220
- 131 + 108089 = 108220
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 108,220 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 108220 first appears in π at position 124,003 of the decimal expansion (the 124,003ordinal-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.
