Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102684, here are decompositions:
- 5 + 102679 = 102684
- 7 + 102677 = 102684
- 11 + 102673 = 102684
- 17 + 102667 = 102684
- 31 + 102653 = 102684
- 37 + 102647 = 102684
- 41 + 102643 = 102684
- 73 + 102611 = 102684
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 102,684 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 102684 first appears in π at position 219,012 of the decimal expansion (the 219,012ordinal-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.
