Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123684, here are decompositions:
- 7 + 123677 = 123684
- 17 + 123667 = 123684
- 23 + 123661 = 123684
- 31 + 123653 = 123684
- 47 + 123637 = 123684
- 53 + 123631 = 123684
- 83 + 123601 = 123684
- 101 + 123583 = 123684
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 123,684 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 123684 first appears in π at position 261,597 of the decimal expansion (the 261,597ordinal-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.
