Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103408, here are decompositions:
- 17 + 103391 = 103408
- 59 + 103349 = 103408
- 89 + 103319 = 103408
- 101 + 103307 = 103408
- 191 + 103217 = 103408
- 317 + 103091 = 103408
- 359 + 103049 = 103408
- 401 + 103007 = 103408
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 103,408 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 103408 first appears in π at position 727,493 of the decimal expansion (the 727,493ordinal-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.
