Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124684, here are decompositions:
- 5 + 124679 = 124684
- 11 + 124673 = 124684
- 41 + 124643 = 124684
- 83 + 124601 = 124684
- 107 + 124577 = 124684
- 191 + 124493 = 124684
- 251 + 124433 = 124684
- 257 + 124427 = 124684
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 124,684 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 124684 first appears in π at position 319,153 of the decimal expansion (the 319,153ordinal-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.
