Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123424, here are decompositions:
- 5 + 123419 = 123424
- 17 + 123407 = 123424
- 23 + 123401 = 123424
- 47 + 123377 = 123424
- 83 + 123341 = 123424
- 101 + 123323 = 123424
- 113 + 123311 = 123424
- 233 + 123191 = 123424
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 123,424 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 123424 first appears in π at position 80,402 of the decimal expansion (the 80,402ordinal-suffix:nd 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.
