Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103666, here are decompositions:
- 23 + 103643 = 103666
- 47 + 103619 = 103666
- 53 + 103613 = 103666
- 83 + 103583 = 103666
- 89 + 103577 = 103666
- 113 + 103553 = 103666
- 137 + 103529 = 103666
- 257 + 103409 = 103666
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 103,666 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 103666 first appears in π at position 375,598 of the decimal expansion (the 375,598ordinal-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.
