Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108420, here are decompositions:
- 7 + 108413 = 108420
- 19 + 108401 = 108420
- 41 + 108379 = 108420
- 43 + 108377 = 108420
- 61 + 108359 = 108420
- 73 + 108347 = 108420
- 127 + 108293 = 108420
- 131 + 108289 = 108420
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 108,420 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 108420 first appears in π at position 88,896 of the decimal expansion (the 88,896ordinal-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.
