Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108790, here are decompositions:
- 29 + 108761 = 108790
- 83 + 108707 = 108790
- 113 + 108677 = 108790
- 233 + 108557 = 108790
- 257 + 108533 = 108790
- 293 + 108497 = 108790
- 389 + 108401 = 108790
- 431 + 108359 = 108790
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 108,790 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 108790 first appears in π at position 772,561 of the decimal expansion (the 772,561ordinal-suffix:st 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.
