Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108090, here are decompositions:
- 11 + 108079 = 108090
- 29 + 108061 = 108090
- 53 + 108037 = 108090
- 67 + 108023 = 108090
- 79 + 108011 = 108090
- 83 + 108007 = 108090
- 109 + 107981 = 108090
- 139 + 107951 = 108090
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 108,090 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 108090 first appears in π at position 973,570 of the decimal expansion (the 973,570ordinal-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.
