Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102304, here are decompositions:
- 3 + 102301 = 102304
- 5 + 102299 = 102304
- 11 + 102293 = 102304
- 53 + 102251 = 102304
- 71 + 102233 = 102304
- 101 + 102203 = 102304
- 107 + 102197 = 102304
- 113 + 102191 = 102304
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 102,304 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 102304 first appears in π at position 603,585 of the decimal expansion (the 603,585ordinal-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.
