Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102404, here are decompositions:
- 7 + 102397 = 102404
- 37 + 102367 = 102404
- 67 + 102337 = 102404
- 103 + 102301 = 102404
- 151 + 102253 = 102404
- 163 + 102241 = 102404
- 223 + 102181 = 102404
- 283 + 102121 = 102404
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 102,404 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 102404 first appears in π at position 670,795 of the decimal expansion (the 670,795ordinal-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.
